1967 Rhondda West by-election
The Rhondda West by-election, 1967 was a parliamentary by-election held on 9 March 1967 for the British House of Commons constituency of Rhondda West in Wales.
The seat had become vacant when the constituency's Labour Member of Parliament, Iorwerth Thomas, died on 3 December 1966, aged 71. He had held the seat since the 1950 general election.
The result of the contest was a victory for the Labour candidate, Alec Jones, who won with a majority of 2,306 over the Plaid Cymru's H. Vic Davies.
Jones represented the constituency until his death in March 1983. No by-election was held because of the imminence of the 1983 general election.
