Marisa Lee Miller (born August 6, 1978) is an American model best known for her appearances in the Sports Illustrated Swimsuit Issues, and her work for lingerie retailer Victoria's Secret. After a stint shooting with photographer Mario Testino for fashion magazines like Vogue, Miller began working for both companies in 2002. As of late 2007, she is a Victoria's Secret Angel, and graced the cover of the 2008 Sports Illustrated Swimsuit Issue to record-setting numbers, accomplishments that have led to her being dubbed the "return of the great American supermodel."

She is also known for contracts with companies like Harley-Davidson and for ranking #1 on Maxim magazine's 2008 "Hot 100" list. Aside from modeling, she is an ambassador for the American Cancer Society.

Born Marisa Lee Bertetta in Santa Cruz, California, Miller attended high school at Aptos High and Monte Vista Christian. She considered herself a tomboy growing up, with mostly male friends and little awareness of anything girly. Out of shyness, she often wore large t-shirts to hide her body and would get fully dressed just to go to the trash can while at the beach.
