Early life:
Cook was born in Minneapolis, Minnesota to Thomas H. Cook, a social worker and former stand-up comic, and JoAnn, a cooking instructor and weaver. Cook attended school at Clara Barton Open, Laurel Springs School and Minneapolis South High School. She began working as a print model at the age of 10, most notably in nationwide advertisements for Target and appearing on the boxes of Milk-Bone dog biscuits.

At the age of 14, Cook began auditioning for acting work. Her modeling agency sent her to read for a short film, 26 Summer Street (1996). She first gained national attention in 1998, when she was featured in a This Is Your Brain on Drugs public-service television advertisement, in which she proceeds to destroy a kitchen with a frying pan as she lists the things that heroin harms. Cook made her debut as an actress in the 1995 film The Baby-Sitters Club, which was based on Ann M. Martin's book series of the same name. Her second movie role was in Tom and Huck, where she portrayed Rebecca "Becky" Thatcher. In 1997, Cook appeared in a leading role in the film Country Justice as a 15-year-old rape victim who is impregnated by her rapist.
Cook's two highest-profile lead roles to date have been in the films She's All That (1999) and Josie and the Pussycats (2001). Cook has also appeared in a number of independent films and in the 2005 television miniseries Into the West.

Cook has provided the voice of Tifa Lockhart in the video games Kingdom Hearts II and Dirge of Cerberus: Final Fantasy VII, as well as the CG movie Final Fantasy VII Advent Children. She also starred in the video for New Found Glory's 2000 single "Dressed to Kill". Cook's latest voice-over role is for the video game Yakuza where she voices the role of Reina, a beautiful barkeep. She has also appeared in Daniel Powter's "Love You Lately".
Cook owns her own production company, Ben's Sister Productions (in reference to her younger brother, an aspiring filmmaker). Cook eventually stepped away from the spotlight to focus on spending time with friends and family. She later returned to mainstream films when she signed on to a new casting agency. Cook was later cast in a role in the big screen adaptation of Nancy Drew, the female lead in the independent sports drama The Final Season, and playing a small supporting lead in Blonde Ambition.
In 2008 she guest-starred in a episode of the USA Network series Psych as Abigail Lytar, an old flame of Shawn Spencer. She returned in the season finale where Abigail and Shawn start dating and has since appeared in many more episodes in the following season.
In February 2010 Rachael Leigh Cook signed on as the female lead in Fox's comedy pilot Nirvana.

Cook has dated actors Ben Foster, Vincent Kartheiser, Ryan Reynolds, Shane West, Rider Strong, Jonathan Rhys Meyers and Colin Hanks. In 2004 she married actor Daniel Gillies. Cook, a vegetarian, lives mostly in Los Angeles with her three dogs, but frequently goes back to visit her family in Minnesota. Cook stated she is strongly thinking about adopting a child from a poor country.
