The Best Alien & UFO Stickers for Your Stanley Cup, Hydro Flask, or Owala (That Look Incredible)
The Best Alien & UFO Stickers for Your Stanley Cup, Hydro Flask, or Owala (That Look Incredible)
Your water bottle goes everywhere with you. The gym. The office. Every meeting, every commute, every outdoor adventure where you're technically an adult but your water bottle tells a more interesting story. Which means the stickers on it are doing a lot of work. They're the first thing people notice, the thing that starts conversations, the shorthand for who you are when you don't feel like explaining yourself out loud.
So: aliens. Obviously.
Whether you believe the truth is out there, you simply appreciate cosmic horror as an aesthetic, or you just want your Stanley Cup to communicate that you are a person of unusual taste, this post is for you. Every design here comes from the Haunted Emporium on Redbubble, and every single one is kiss-cut vinyl, water-resistant, and made to survive whatever your water bottle goes through.
Here are the 10 best alien and UFO stickers for your Stanley Cup, Hydro Flask, or Owala.
1. Alien Beaming Up Kitty - The Crowd Favourite
If you only put one sticker on your water bottle from this entire list, make it this one. The Alien Beaming Up Kitty is the rare design that works for everyone, the sci-fi fan, the cat person, the retro art lover, the person who just wants something on their Stanley that makes people smile in the coffee queue.
A classic flying saucer, neon yellow rim, multicolored dome, pink and yellow underside, beams down a column of rainbow light onto a patch of glowing grass below. In the center of that beam: a small black cat, caught mid-abduction, looking neither alarmed nor particularly impressed. Because of course it isn't. It's a cat.
The palette is pure retro pop-art joy, hot pink, neon yellow, teal, lime green, and electric blue. The sticker outline is clean. The composition is perfectly balanced. It's the kind of design that looks like it was always going to exist, and now that it does you're surprised you survived without it.
Best size for water bottles: Large (3–4 inch) on a 40oz Stanley or Hydro Flask where the full detail can shine. Also works beautifully on a phone case or laptop.

2. Space Cat - The One That's Both Creepy and Cute
Some of us contain multitudes. Some of us are simultaneously a cat and an alien. The Space Cat understands.
A classic black cat silhouette, ears, whiskers, the full shape, but the face is pure extraterrestrial: a round green head with almond-shaped alien eyes, the surface a soft watercolour wash of teal and sage scattered with faint gold star-dots. The black cat body grounds it. The alien face elevates it. Together they create something that feels like the mascot of a very specific and very good corner of the internet.
On a water bottle this design works beautifully in medium format, big enough to be identifiable, compact enough to sit alongside other stickers without overwhelming them. It's also a natural conversation starter: people see it, tilt their head slightly, then smile. That's the sequence you want from a sticker.
Pairs naturally with the Alien Beaming Up Kitty for a full alien-cat theme on one side of your bottle.
Best size for water bottles: Medium (2–3 inch), readable up close, distinctive from a distance

3. Astral Alien - The Mysterious One
A cosmic entity floats in its own atmospheric haze, teal and blue-green smoke forming a vaguely humanoid shape with a simplified skull-like face, two enormous glowing yellow eyes, a small dot of a mouth. The form has an organic, almost gaseous quality, like something that exists between states. The starfield texture scattered throughout gives it depth and distance. The dark purple background makes those yellow eyes glow with real intensity.
This is the alien for people who take their extraterrestrial aesthetics seriously. Not cartoonish, not threatening, something older and more interesting than either. It sits in the cosmic horror tradition, the ancient astronaut tradition, the "what if the universe contains things we genuinely can't categorize" tradition. On a dark water bottle it looks like it's emerging from the void, which is exactly the effect you want.
Best size for water bottles: Medium-large (3 inch) — the detail rewards proximity
4. Pink Hellion - The Sweetest Eldritch Horror You'll Ever Own
Lovecraftian horror has never looked this approachable, and honestly we're better for it.
The Pink Hellion is a compact, chunky creature that sits in the precise overlap between Cthulhu mythos and spooky cute, a rounded pink-coral body with a tentacled face, hollow eye sockets, and small nostrils, flanked by two small gold-scaled wing stubs that suggest flight as a theoretical option. The texture is granular and slightly glittery, the palette warm coral-to-deep-pink, the gold of the wings providing the perfect complementary accent. It's round. It's pink. It has tentacles instead of a mouth. It should not be this endearing and yet here we are.
The Pink Hellion is the gateway sticker, the one that introduces cosmic horror aesthetics to people who didn't know they were into cosmic horror aesthetics. On a pink Stanley Cup it creates a moment of perfect visual harmony. On any other color bottle it pops dramatically. It's also the sticker that will get the most comments from coworkers who thought they weren't into this kind of thing until they saw it up close.
Best size for water bottles: Medium (2–3 inch), the round format is naturally compact and satisfying

5. Alien Hazmat - Bold, Graphic, and Slightly Threatening
A flat, graphic skull-creature rendered in high-contrast neon yellow on a rich dark ground, small horns at the temples, asymmetric eyes with different detailed markings inside each socket (one with lines, one with a butterfly motif that should not be there and somehow makes everything stranger), triangular nasal cavity, a row of stubby teeth at the bottom. The whole thing is surrounded by a faintly textured dark shape suggesting a body or perhaps a hazmat suit. The neon yellow background makes the design read as a warning label from a dimension with different safety standards.
The asymmetric eye detail is what makes this one special, it rewards the close look, the moment when someone leans in to examine your water bottle and realizes the eyes are telling two different stories. Graphic, weird, precise. Exactly right.
Best size for water bottles: Medium (2.5–3 inch), the flat graphic style reads cleanly at any size.
6. Alien Mothership - Minimal, Iconic, and Immediately Recognizable
The Alien Mothership is a masterclass in graphic minimalism, a classic flying saucer shape rendered in deep matte black with a starfield texture scattered across the dome, the belly of the craft a band of neon yellow-green with triangular window shapes arranged like teeth in a wide lateral eye. Below, three landing struts suggest imminent contact. The acid green background makes the black shape sit with perfect visual contrast and maximum pop.
This is the sticker for the person who wants alien content that feels designed rather than illustrated, clean, bold, badge-like. It has the quality of something that could be a logo for a very unusual organization, which is part of its appeal. It reads clearly from across a room, looks exceptional at any size, and pairs naturally with the more detailed creature designs in this list to provide visual contrast and breathing room.
A UFO sticker is almost obligatory on a water bottle with this kind of theme. This is the one to use.
Best size for water bottles: Medium (2.5–3 inch), the silhouette is strong at any scale.

7. Swamp Thing - The Creature From the Bottom of the Water Bottle
The Swamp Thing is a creature face of tremendous character, a green, scaly, textured head covered in overlapping scales and ridge-lines, enormous golden-yellow eyes bulging with the specific expression of something that has been watching from the swamp for a very long time and finds it largely unremarkable, and a vast mouth full of misaligned white teeth arranged in a grin that suggests either friendliness or the moment just before something goes badly wrong. The muted purple background makes the green really sing.
On a water bottle this design has an obvious and excellent joke to offer: what's in the bottle, exactly? The Swamp Thing seems to know. It's not telling. It does seem delighted about something.
Beyond the humor, this is genuinely beautifully rendered creature art, detailed, expressive, with real personality in the face. For fans of creature features, B-movie horror, swamp horror, and anyone who has ever spent time near water and had the feeling something was watching, this is the sticker that gets it.
Best size for water bottles: Large (3–4 inch), the face detail deserves real estate.

8. Space Dude - Retro Cosmic Cool
A rounded alien skull face, neon lime green, flat almond eyes filled with starfield black, a triangular nasal bone, sits atop a layered teardrop body built of horizontal bands: teal, deep red, orange, each layer slightly receding, suggesting a rocket launch in reverse or a costume built from the colors of another world. The deep purple background grounds the whole composition in space. The overall shape is clean and graphic with a mid-century space-age quality that feels both nostalgic and completely fresh.
For fans of retro sci-fi, space age aesthetics, vintage NASA poster art, and the general cultural moment where cosmic imagery and dark art have converged into something genuinely compelling, Space Dude lands exactly right. It looks exceptional on a water bottle where the vertical format suits its proportions, and even better as a phone case where the detail can breathe.
Best size for water bottles: Medium-large (3 inch) to honor the layered body detail.

9. Cthulhu - For the Lovecraft Fan Who Takes Their Hydration Seriously
Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn. And also, stay hydrated.
The Cthulhu design renders the Great Old One in bold, graphic form that honors the source material while creating something visually clean enough to work as a strong sticker. Deep teal-green skull-face, symmetrical tentacles curling from the lower jaw, pale glowing eyes that suggest vast ancient intelligence operating on a scale where your water bottle is cosmically insignificant but somehow also noticed. The mustard yellow background makes the teal sit with genuine visual drama.
Cthulhu stickers are a perennial presence in the sci-fi, horror, and tabletop gaming communities, and for good reason, the design language is immediately recognizable to the people who care about it and intriguing to the people who don't yet. This version is bold and graphic enough to work at sticker scale without losing any of its presence. For Lovecraft fans, Call of Cthulhu players, cosmic horror enthusiasts, and anyone who finds the idea of unfathomable ancient entities a comforting alternative to thinking about their inbox, this is the one.
Best size for water bottles: Large (3–4 inch), the tentacle spread needs room.

10. Alien Raccoon — The One Nobody Expected and Everyone Loves
The raccoon has become a cultural figure of genuine significance, chaotic, nocturnal, operating outside conventional social contracts, thriving in the spaces between things. The Alien Raccoon takes that energy and adds a layer of cosmic weirdness that, frankly, feels overdue.
A raccoon face redrawn as an alien, the distinctive mask markings transformed into alien eye shapes, glowing white and angular, the characteristic raccoon band across the eyes now reading as an extraterrestrial feature rather than an earthly one. The coloring is gold-olive against a matte black, the whole composition contained in a circular format with a scattered starfield. A sage green background gives it a naturalist-illustration quality that contrasts brilliantly with the alien reinterpretation of the face.
This design is for the raccoon person (a passionate and growing community), the cryptid fan, and anyone who has looked at a raccoon rummaging through a bin at 2am and thought "there is something fundamentally unknowable about you." On a water bottle it creates the best possible conversation: "is that a raccoon?" Yes. Also no.
Best size for water bottles: Medium (2.5–3 inch), the circular badge format is compact and versatile.
