The Kensington by-election, in Kensington, on 14 July 1988 was held after the death of Conservative Member of Parliament (MP) Brandon Rhys-Williams. Normally a relatively safe Conservative seat, it was narrowly won by Dudley Fishburn, who would retain the seat in 1992. It was the first by-election of that parliament, which had begun after the general election of June 1987, and would last until the next election in April 1992.
