The Leeds City Council elections were held on Thursday, 2 May 1991, with one third of the council and a vacancy in Horsforth to be elected.

The upsurge in Labour support recorded the previous year mostly unwound, allowing the Conservatives and the renamed Liberal Democrats a more successful election - although the latter also looked to be recovering from their disastrous merger, fielding a more convincing slate and gaining a moderate rise in their vote. The surprise Conservative losses of 1990 election were all defended this time round - although only narrowly in the case of Weetwood, with Halton and Pudsey North being much safer and Aireborough actually a gain from the Lib Dems. Labour managed a gain a seat apiece from the main opposition parties, with a comfortable win in Burmantofts from the Lib Dems and snatching the last Conservative seat in Morley North to further extend their record majority.

Meanwhile, the Greens stood in over a third of the wards - their strongest slate in over a decade, and the Liberals won third place in each of the handful of wards they stood in.
