As a child, Cuoco was once a nationally-ranked amateur tennis player, a sport she took up when she was three years old but had to give up in 1992, when she was six. Her role as Maureen McCormick in the 2000 TV movie Growing Up Brady brought her much attention, as well as a role on the CBS sitcom Ladies Man. In 2004 in addition to her role on 8 Simple Rules in which she played a teenager, she had starring roles on the NBC miniseries, 10.5, on the ABC Family original movie, Crimes of Fashion, and in the independent film, Debating Robert Lee. In 2000 she starred in the Disney Channel Original Movie Alley Cats Strike.
Cuoco was named number 77 on FHM-Us 100 Sexiest Women in 2005 and number 21 in 2008. She was also named number 28 on Maxim's annual Hot 100 list in 2010 and number 13 in 2011.
She began voicing the character of Brandy Harrington on the Disney Channel's cartoon, Brandy and Mr. Whiskers, later in 2004.
Cuoco played Bridget Hennessy on the ABC sitcom 8 Simple Rules. Bridget was the eldest child, despite Cuoco being six years younger than her on-screen little sister (Amy Davidson), and was portrayed as "the most beautiful girl in the school." She had several boyfriends throughout the series and used her feminine wiles to exert significant control over the boys she encountered.
In the eighth season of the hit cult TV show Charmed, Cuoco appeared as Billie Jenkins a young powerful witch who was also one of whitelighter Paige Matthews' charges. Executive producer Brad Kern stated Kaley's character was initially brought in as a possible spin-off. In 2004 Cuoco co-starred in the movie The Hollow with Nick Carter and Kevin Zegers.
In September 2007, Cuoco began a starring role in the CBS sitcom The Big Bang Theory. She plays Penny, an aspiring actress and employee at The Cheesecake Factory who lives across the hall from two nerdy scientists, Sheldon (Jim Parsons) and Leonard (Johnny Galecki). Prior to the 2010–2011 season, she earned $60,000 an episode for the series, the same as Johnny Galecki and Jim Parsons. In 2010 the cast negotiated a raise for each actor to make $200,000 per episode. On September 13, 2010, she broke her leg in a horse-riding accident and missed two episodes of the series.
Cuoco also starred in the Lifetime film To Be Fat Like Me, which premiered on January 8, 2007. She also played a minor role in the Prison Break episodes "The Message" and "Chicago" as well as taking the leading female role in the comedy horror spoof Killer Movie in 2008.
In 2011 Cuoco appeared in Allure magazine's annual "Naked Truth" feature. The photograph, which appeared in the May issue, was taken by Patrick Demarchelier. That same year, she appeared in the films Hop and The Last Ride. She was also chosen to host both the 2011 Teen Choice Awards and the 2012 People's Choice Awards.
While working on The Big Bang Theory, Cuoco dated co-star Johnny Galecki for two years. They kept their relationship private until they broke up.
In October 2011 Cuoco announced her engagement to boyfriend Josh Resnik, an addiction specialist and former bassist for Danzig. However, in March 2012 she revealed that she was no longer engaged.
Cuoco has admitted that she is a big fan of both Game of Thrones and Harry Potter.
