Blythe Duff (born 25 November 1962 in East Kilbride, South Lanarkshire) is a Scottish actress, best known for her role as Jackie Reid in the STV drama, Taggart. Her career started with The Scottish Youth and Community Theatre which took her all over Glasgow but earned her only £25.00 a week.

Blythe worked in the theatre for 7 years before she landed the role in Taggart. After appearing as a community WPC in Death Comes Softly, it was decided that the character would be promoted and seconded to CID.

Blythe has become the longest serving member of the Taggart cast after James MacPherson left the show in early 2002.

Some would say it was appropriate that in March 1998 Blythe married ex Detective Sergeant Tom Forrest. Somehow the police had always featured in her life; the dream of being a mounted police woman, playing a police woman on TV and then settling down with her very own genuine policeman.
