Duncan Fraser is a British-born Canadian actor. He is most noted for his performance in the 1985 film Overnight, for which he was a Genie Award nominee for Best Supporting Actor at the 7th Genie Awards in 1986, and his regular role as Staff Sgt. Regan in Da Vinci's Inquest, for which he was a Gemini Award nominee for Best Supporting Actor in a Drama Series at the 15th Gemini Awards in 2000.

Born in Manchester, England, Fraser planned to study aeronautical engineering at London University, but switched to psychology after finding engineering too technical and mathematical. Following university he travelled around the world for a number of years, before settling in the Vancouver area in 1974 and working as an actor. He spent a number of years as director of the Nanaimo Theatre Festival, and as associate director of Vancouver's Fend Players theatre company.
