Trevor Alec Jones (12 August 1924 – 20 March 1983) was a British Labour Party politician.
Jones was born in Clydach Vale and educated at Rhondda Boys' Grammar School. After obtaining a teaching qualification at Bangor Normal College, he taught from 1947 until 1967, when the death of the local MP, Iorwerth Thomas, whose political agent Jones had been, created a vacancy which resulted in his own selection.
Jones was Member of Parliament for Rhondda West from the 1967 Rhondda West by-election until the constituency was abolished in 1974, and for Rhondda from 1974 until he died in office shortly before the 1983 general election. He was a junior minister for Social Security from 1974 to 1975 and for Wales from 1975 to 1979.
Jones had suffered from a heart condition for some years prior to his death at the age of 58, which occurred at his home in Tonypandy.[1]
