The 31-year-old, who married concert promoter Simone Sestito in June last year, admitted that she can't wait to start having children.
"Everybody wants a child," she told People. "I want at least two children, maybe in another year or so.
"Who knows, I might end up having five and being this crazy woman with all these children. I think that would be the ultimate experience for me."
Suvari was previously married to cinematographer Robert Brinkmann between 2000 and 2005.
The actress is best known for her roles in the films American Beauty and American Pie, as well as a guest starring part on the HBO series Six Feet Under.
