Victor Joseph Garber (born March 16, 1949) is a six-time Emmy Award-nominated Canadian film, stage and television actor and singer. Garber is perhaps best known for playing Jack Bristow in the television series Alias and Thomas Andrews in James Cameron's Titanic.

Garber was born in London, Ontario, Canada. His mother, Hope Garber (née Wolf), was an actress and singer. Victor was also her caregiver until her death from Alzheimer's disease. When Garber was 12 he was diagnosed with Type 1 Diabetes.

Garber began acting at the age of nine, joining the University of Toronto's Hart House at age 15. In 1967, he formed a folk band called The Sugar Shoppe with Peter Mann, Laurie Hood and Lee Harris. The group enjoyed moderate success, even performing on The Ed Sullivan Show and The Tonight Show Starring Johnny Carson before breaking up. He has worked in various American and Canadian movies and television, including James Cameron's Titanic (1997), in which he perfected a Northern Irish accent to play the shipbuilder Thomas Andrews, and CTV's E.N.G. (1991–1993), on which he had a recurring guest role.
