Suvari was born in Newport, Rhode Island. She is the daughter of nurse Candice (née Chambers) and psychiatrist Ando Ivar Süvari [et]. Her mother is of Greek descent, while her father was an Estonian from Pärnu. She has six siblings. Suvari began modeling with Millie Lewis Models and Talent as a preteen and soon after appeared in a Rice-A-Roni commercial. The family later relocated to Charleston, South Carolina, where her brothers attended The Citadel. Suvari was considering becoming an archaeologist, astronaut, or doctor when a modeling agency stopped by her all-girls school, Ashley Hall, to offer classes. By the time she started acting, she had been modeling for the New York-based Wilhelmina agency for five years. Suvari relocated to California and attended Providence High School in Burbank, graduating in 1997.

Suvari began acting with guest appearances in television series such as Boy Meets World and ER at the ages of 15 and 16, respectively. She also appeared in a number of episodes of the show High Incident, and played a girl infected with HIV in a one-episode appearance in Chicago Hope. She made the transition to film with the role of Zoe in the 1997 independent coming-of-age drama Nowhere, directed by Gregg Araki and co-starring James Duval, Rachel True, Heather Graham, and Ryan Phillippe. Also in 1997, she had a supporting part in the independent film Snide and Prejudice, which premiered at the Cannes Film Festival, and had a brief part in the thriller Kiss the Girls, opposite Morgan Freeman and Ashley Judd. She next appeared in the independent dramedy Slums of Beverly Hills, as a teenaged neighbor of a Jewish girl struggling to grow up in the late 1970s. The film received a limited release, and has developed a cult following. Suvari met Natasha Lyonne on the set of Slums, with whom she would later appear in the American Pie films. She subsequently played a teenager who commits suicide in the horror sequel The Rage: Carrie 2 (1999), and appeared as the daughter of an NTSB investigator in the disaster thriller NBC miniseries Atomic Train (1999), although both productions were panned by critics.

Her breakthrough came in 1999, with significant roles in two highly successful films —the teen sex comedy American Pie and the drama American Beauty. In American Pie, she starred with Jason Biggs, Shannon Elizabeth, Chris Klein, and Natasha Lyonne, portraying a virgin and innocent choir girl named Heather. While critical response was mixed, the film was a commercial success, grossing $235 million worldwide.

In American Beauty, directed by Sam Mendes and co-starring Kevin Spacey, Annette Bening, Wes Bentley and Thora Birch, Suvari took on the role of Angela Hayes, a vain teenage girl who becomes the object of infatuation of a man experiencing a midlife crisis. The New York Times described her character as "stimulus enough for [Spacey's character] to wake up out of a marriage-long coma and start considering life's livelier possibilities". The film received widespread critical acclaim, and received the Academy Award for Best Picture. American Beauty made $356 million globally and earned Suvari a BAFTA Award nomination for Best Supporting Actress. Suvari and her American Beauty co-stars Wes Bentley and Thora Birch presented the 2000 Oscar for Best Documentary short subject.
