Jenna Jameson is an American pornographic actress and entrepreneur who has been called the world's most famous porn star and "The Queen of Porn". She started acting in erotic films in 1993 after having worked as a stripper and glamour model. By 1996, she had won the three top newcomer awards from pornographic film industry organizations. She has since won more than 20 adult film awards, and has been inducted into both the X-Rated Critics Organization (XRCO) and Adult Video News (AVN) Halls of Fame.

Jameson founded pornographic entertainment company Club Jenna in 2000, with Jay Grdina, whom she later married.

Jameson is also noted for her relative success in crossing over into mainstream celebrity, starting with a minor role in Howard Stern's 1997 film Private Parts. Her mainstream appearances continued with guest-hosting E! television, an award-winning voice role in the 2002 video game Grand Theft Auto: Vice City, and a recurring role on the 2003 NBC television series Mister Sterling. Her 2004 autobiography, How to Make Love Like a Porn Star: A Cautionary Tale, spent six weeks on The New York Times Best Seller list.

Jameson says that she started acting in pornographic films in revenge for her boyfriend, Jack, cheating on her.
