She hosts the Cooking Channel series Dinner at Tiffani's (2015–2017) and the MTV comedy clip show Deliciousness (2020–present).

Thiessen was born in Long Beach, California, the daughter of Robyn (née Ernest), a homemaker, and Frank Thiessen, a park designer and landscape architect.^[2][3] She has credited her brother, Todd, as one of her most important sources of inspiration, and her mother and grandmother as role models.^[4] Thiessen told InStyle magazine: "I'm a mutt. I have so much of everything in me, and half of it I don't even know. German on one side, Greek, Turkish and Welsh on the other. My mom is very olive-skinned; I get my blue eyes from my dad."^[5][6]

Thiessen participated in beauty pageants during her childhood and was crowned Miss Junior America in 1987. The following year, she appeared on the cover of Teen magazine, having won the magazine's "Great Model Search". In 1989, she was named Cover Girl's "Model of the Year", and landed her first role of Kelly Kapowski on NBC's television sitcom Saved by the Bell, starring until its end in 1993. The success of the show gave her career a boost and Thiessen received Young Artist Award nominations for Outstanding Young Ensemble Cast in 1990 and Best Young Actress Starring in an Off-Primetime Series in 1991 and 1993.^[7][8][9] Simultaneously, Thiessen guest-starred on series such as Married... with Children, Charles in Charge and Step by Step. In 1992, she starred in her first television movies Saved by the Bell: Hawaiian Style and A Killer Among Friends, making her film debut in Son in Law in 1993. She then continued with starring in spin-off Saved by the Bell: The College Years in its single season (1993–94) and in television movie Saved by the Bell: Wedding in Las Vegas (1994), which marked the end of the original Saved by the Bell series.

In 1994, after her tenure on Saved by the Bell had ended, Thiessen landed the role of Valerie Malone in Fox's Aaron Spelling-produced hit teen-drama Beverly Hills, 90210, to fill the void after Shannen Doherty's departure. She was the first actress to join directly the main cast of the show and portrayed Valerie until 1998, when she left in the early episodes of the ninth season of the show. While starring in 90210, Thiessen began to take on continuous dramatic leading roles in television films: The Stranger Beside Me (1995) and She Fought Alone (1995), Sweet Dreams and Buried Secrets in 1996. After her departure from the show, she appeared in a number of films, including Speedway Junky (1999), From Dusk Till Dawn 2: Texas Blood Money (1999), Love Stinks (1999) and The Ladies Man (2000); she also guest-starred on NewsRadio (1999), Two Guys and a Girl (2000), Just Shoot Me!

In 2000, she was featured in the music video for "You're a God" by Vertical Horizon, portraying a beauty pageant contestant, in her first music video appearance. That year she also dropped her middle name which she had been including professionally for many years and is now credited as simply Tiffani Thiessen.^[10] Thiessen was Spelling's first choice to replace Doherty in the series Charmed in 2001, but she refused his offer because she was hoping the NBC pilot for Everything But the Girl would be picked up.^[11] The role eventually went to Rose McGowan.

Meanwhile, Thiessen starred in direct-to-video parody film Shriek If You Know What I Did Last Friday the Thirteenth (2000) and in television movie Everything But the Girl (2001), before appearing in the Woody Allen-directed film Hollywood Ending (2002) and starring in action-drama series Fastlane (2002–03) as Wilhelmina 'Billie' Chambers, for which she received a Teen Choice Award nomination for Choice TV Actress – Drama/Action Adventure.^[12] In 2003, she launched her production company Tit 4 Tat Productions, producing and directing the short film Just Pray in 2005,^[13] which earned distinctions at several film festivals,^[14] including winning Best Score at the Rhode Island International Film Festival, an Academy Award qualifying festival. The original motion picture soundtrack album, co-produced by Thiessen and Al Gomes of Big Noise, was placed on the Official Ballot for the 49th Annual Grammy Awards by The Recording Academy in several categories including Best Compilation Soundtrack Album For Motion Picture, Television or Other Visual Media.^[15]

Later on, she starred in television movies Stroller Wars (2006) and Pandemic (2007), she joined the cast of ABC's drama What About Brian (2007) for its last five episodes and starred in the science fiction film Cyborg Soldier (2008).

On June 7, 2017, Thiessen was cast as Lori Mendoza, mother of the Mendoza family on the multi camera Netflix sitcom Alexa & Katie, which premiered its first two seasons on March 23 and December 26, 2018.^[20] In 2021, at the 48th Daytime Creative Arts Emmy Awards, she was nominated in the category of Outstanding Performance by a Supporting Actress in a Daytime Fiction Program.^[21]

Thiessen was a teen idol during the 1990s, starting from her role as cheerleader Kelly Kapowski on Saved by the Bell and then playing bad girl Valerie Malone on Beverly Hills, 90210. In a much-discussed moment, Justin Bieber appeared wearing a T-shirt with a photo of Thiessen in her Saved by the Bell days at the 2011 MuchMusic Video Awards,^[26] admitting his admiration for her. Basketball player Chris Paul also revealed publicly that he was a fan of Thiessen back then, when she sent him an autographed Saved by the Bell-era photograph of herself for his 29th birthday in 2014.^[27]

Thiessen dated her Saved by the Bell co-star Mark-Paul Gosselaar (who played Zack in the show). She also dated Mario Lopez, who played A.C. Slater, from 1991 to November 1993.^{[28][29][30][31]}

Garth and Thiessen's friendship has since come to an end.^[38] Her friendship with fellow 90210 star Tori Spelling also ended after Spelling's marriage to her first husband ended.^[39]
