The Pontypridd by-election, 1989 was a by-election held in Wales on 23 February 1989 for the House of Commons constituency of Pontypridd in Mid Glamorgan. The by-election was caused by the death of the constituency's Labour Party Member of Parliament (MP) Brynmor John on 13 December 1988. The result was a Labour Party hold, with Dr Kim Howells winning a majority of almost 11,000 votes. Whilst out canvassing for the Conservative party, neighbouring MP Sir Raymond Gower died, which resulted in the Vale of Glamorgan by-election.
