The 1984 Cynon Valley by-election was a parliamentary by-election held on 3 May 1984 for the British House of Commons constituency of Cynon Valley.

Previous MP

The seat had become vacant on 10 February 1984. The constituency's Labour Member of Parliament (MP), Ioan Lyonel Evans (10 July 1927 – 10 February 1984), had died at the age of 56.

Evans was a Labour Co-operative politician. He was educated at Llanelli Grammar School and Swansea University College. He served on the West Bromwich education committee and acted as Labour Party agent for the general elections in 1955 and 1959 in Birmingham Small Heath.
