Jacqueline Susan McKenzie (October 24, 1967 in Sydney, Australia) is a film and television actress.
McKenzie made her film debut in the 1987 film Wordplay, made a strong impression in Romper Stomper (1992), and over the next couple of years came to be regarded as one of Australia's most promising young actresses.
She received Australian Film Institute Award nominations for her roles in Stark, This Won't Hurt a Bit (both 1993), The Battlers and Traps (both 1994) before winning two awards in 1995 for "Best Actress in a Television Drama" for Halifax f.p: Lies of the Mind, and Best Actress in a Leading Role" for Angel Baby.
With this success she ventured to the United States and secured a Green Card, as a "Person of Extraordinary Ability". Her subsequent acting roles in films such as Deep Blue Sea (1999) and Divine Secrets of the Ya-Ya Sisterhood (2002) failed to establish her in Hollywood.
In 2004 she played the lead female role in the television production of The 4400, one of the year's biggest successes.
