Lisa Olivia Munn is an American actress, model and television personality.

She began her career being credited as Lisa Munn. However, since 2006, she has been using the name Olivia Munn professionally.

Lisa Olivia Munn was born in Oklahoma to mother Kim Munn and father Sam Munn. She is of Chinese descent on her mother`s side and of Caucasian descent on her father`s.

Munn moved back to the United States, settling in Los Angeles, California to pursue an acting career. In 2004, she interned at Fox Sports Net and worked as a sideline reporter for college football and women`s basketball. She has gone on to say that she disliked the experience, explaining "I was trying to be something I wasn`t, and that made me really uncomfortable on live TV." Munn had also gained a small role in the straight to video horror film Scarecrow Gone Wild. She also stars in the music video Hello Tomorrow by the band Zebrahead.

In late 2005, Munn began her portrayal of Milly Acuna, a teen surfer, over two seasons of the TV drama Beyond the Break on The N network. She enjoys surfing and continues to practice the sport. She originally auditioned for the part of Kai, but the producers wanted a "local girl". She also appeared in the film The Road to Canyon Lake.
