Whether she's sporting a bikini in hit TV shows like The White Lotus or blockbuster movies such as Baywatch, Alexandra Daddario is constantly showing us that she can rock a bikini like no other. The actress frequently shares snaps in ensembles that show off her svelte figure, and of course, no two bikinis are the same – though the Hollywood star looks unbelievable in every single one of them.
From kicking back by her pool at home in a casual number to posting breathtaking holiday photos looking just as stunning as the backgrounds behind her, Alex has clearly mastered the art of the perfect bikini picture, giving fans some serious summer holiday inspiration.
Join HELLO! as we take a look at the Baywatch babe's most sizzling bikini photos, from daring skin-toned looks to radiant jewel-toned swimwear that shows off her enviable physique.

Poolside paradise
We're not sure what we’re more jealous of – Alex's effortless sun-soaked style or that stunning turquoise water. The Mayfair Witches star kept it casual for an afternoon by the pool, opting for a silver-grey ensemble alongside cascading beach waves. "Taken by the man who can make even the kitchen pantry fun," she captioned the picture, likely alluding to her husband, film producer Andrew Form.
Though it was revealed they split in February 2026, the brunette beauty has no shortage of furry friends to keep her company – in her spare time, she's known to foster dogs, often sharing sweet snaps on her Instagram. Radiant with a heart of gold – leave some for the rest of us!

Gilligan goddess
You'd be forgiven for thinking this was a glossy editorial cover shoot! Alex took a trip in 2023 to Gilligan's Island, a stunning, mangrove-shrouded island off the coast of Guánica, Puerto Rico, best known for its crystal-clear waters – an ideal location to lounge on the beach and snap some Instagram pics.
The actress donned a simple black bikini with a pair of matching sunglasses, leaving her hair loose as she posed on the island's golden sand, basking in the rays. Later on, she changed into a champagne-coloured slinky midi dress, perfectly encapsulating island chic as she leaned against a palm tree. Be right back, just booking a summer holiday…

A diamond in Dior
Dior's exclusive cabana pop-up at The Beverly Hills Hotel was already giving us major Barbie energy, but adding Alex to the mix made it feel like a certified dreamhouse.
The True Detective actress was a guest of honour at the luxury poolside space in 2023, decked out in a Dior ensemble that perfectly complemented the opulent space. Alex's pink-patterned, purple-toned bikini showed off her toned figure, while the contrasting pink hat was equal parts fashionable and a necessary addition in the California sun. The star also wore a white ensemble as she arrived at the event, complete with a Dior tote bag and her pooch tucked under her arm, nailing off-duty glamour.

While her Hawaiian holiday didn't go quite the way she planned in The White Lotus, Alex clearly fell in love with the state after filming the show there and decided to have a real-life do-over.
The star shared this striking pic from her time away, relaxing in a pool with the rich landscape of The Aloha State behind her – though her stunning swimsuit is equally as eye-catching. Alex opted for a three-toned purple ensemble for her tropical trip, which fit the toned actress like a glove. Hawaii likely became even more special for the star as she later received her very first primetime Emmy nomination that same year for her performance in The White Lotus as Rachel Patton.

Pre-Emmy's dip
Only Alex could capture an action shot like this and still look like a supermodel. "Emmy weekend jump!" she captioned the fun-filled shot, featuring the actress mid-jump into her pool.
For the special weekend, Alex chose a casual two-piece that still oozed Hollywood glamour, with the slinky yellow number featuring a single shoulder strap, complete with her brown locks billowing behind her as she took the plunge (literally). After some much-needed pre-awards show R&R, the star was ready to hit the red carpet in Los Angeles; while she didn’t pick up an award, you can't really lose when this is how you look in a candid action shot…

Lakeside model
It's no surprise that Alex is an accomplished model, and the star joined forces with intimate apparel brand Aerie in 2022 for a lakeside swimwear shoot that had us seriously ready to spend our money.
In a snap shared to Instagram, Alex wore a two-toned zebra-print bikini in bold shades of green that complemented her dark hair beautifully; it was also a family affair, with Alex's sister Cat joining the shoot alongside her in an equally stunning one-piece. "I think it's so wonderful that Aerie is a brand that doesn't photoshop their models," she previously told People of her partnership with the brand, adding that it's important to always "be easy on yourself".

Possibly one of the very few people ever who could pull this shade of beige off, Alex showed off a nude-toned two-piece from her extensive bikini collection that was quite the contrast to the many colourful numbers she'd debuted on Instagram before.
Unsurprisingly, the Why Women Kill star was glowing as she lounged poolside with fellow actress Kate Easton; the star's daring swimsuit appears to be from The Saltwater Collective, whom she tagged in the caption, so anyone who'd like to try out this head-turning ensemble can grab one of their own.

Alex looked practically unreal in her 2017 movie Baywatch, which featured an A-list cast including Zac Efron, Kelly Rohrbach and more. A revival of the Pamela Anderson-led series from the '90s, Alex sported a toned and tanned physique that was, of course, clad in many bikinis during the course of filming.
The actress posed with her co-star, Dwayne "The Rock" Johnson, for a behind-the-scenes snap on Instagram, wearing a pair of black micro-shorts and a blue zebra-print crop top; the activewear-inspired ensemble looks sleek and perfectly pool-ready, but we can't seem to take our eyes off the star's abs and arm muscles, plus her radiant beach-ready tan. Workout routine, please (and don't worry Dwayne, you look great too!)

Fitness queen
With fans like us wanting to know how she got in Baywatch babe shape, Alex graced the cover of Women's Health in 2017 to give us a glimpse into her prep routine for the film.
"For Baywatch, I started doing weight training, which I had never done before, and I saw a huge difference," she told the publication; the star was a testament to her workout routine on the front cover, grinning in a skimpy blue two-piece that brought out the colour of her striking eyes. "I spent 3 months in bathing suits so I completely revamped my normal yoga twice a week/ice cream every night lifestyle," she wrote in her Instagram caption, adding that she "pretty much eats tacos every day". Right…

The beach-loving beauty evidently loves posting bikini photos with equally breathtaking backgrounds, but this one might just have to take the cake.
Alex put her Baywatch training to good use, pulling off an impressive backbend in an oceanside pool as she basked in the sunset, surrounded by rolling hills and nature. While we'd love to know what style of bikini she has on, the picture – which almost resembles a painting – perfectly encapsulates the Hollywood star's love of all things summertime and is evidently just one of many gorgeous snaps she shares celebrating nature (while always looking fabulous).
