Paulina Mary Jean Gretzky (born 19 December 1988 in Los Angeles, California) is an American model and pop singer.

Gretzky was born five months after her parents - former NHL player Wayne Gretzky and actress Janet Jones - married in a lavish ceremony broadcast live throughout Canada.

She sang Sarah McLachlan`s "I Will Remember You" at the Edmonton Oilers-Montreal Canadiens Heritage Classic game at Commonwealth Stadium before 57,167 fans. She performed for the first time in public the night before the Oilers-Canadiens outdoor game. Ron MacLean reported that Gretzky sent a tape of the performance to the producer of the event.

She made her modelling debut on the August 2005 cover of Flare. She and Janet appear in the movie Alpha Dog.

Her song "Collecting Dust" was featured on MTV`s Laguna Beach: The Real Orange County. It has since been released on iTunes.
