Talfryn Thomas (31 October 1922 - 4 November 1982) was a Welsh character actor best known for a variety of supporting roles on British television of the 1970s.
Thomas was born in Swansea, West Glamorgan, Wales. He excelled at playing quirky and sometimes seedy Welshmen. His distinctive appearance was enhanced by his protruding front teeth, which earned him the nickname 'Talf The Teef'. Thomas was a regular on Ken Dodd's BBC radio comedy show and The Ken Dodd Laughter Show, with Rita Webb and Pat Ashton, but is probably best remembered for his role as Private Cheeseman, a member of the Home Guard in later episodes of Dad's Army. In 1975 he featured in several episodes of the first series of the cult BBC TV series Survivors as Tom Price. He also appeared with Jon Pertwee in the Doctor Who serials Spearhead from Space and The Green Death.
Thomas died from a heart attack on November 4, 1982, four days after his 60th birthday.
