The office of deputy leader of the Liberal Democrats (officially deputy leader of the Liberal Democrat Parliamentary Party) is a position within the Liberal Democrats, a liberal political party in the United Kingdom. The position of Deputy Leader has never formally existed in the party constitution, however since the party's foundation, the Liberal Democrat parliamentary group in the House of Commons have usually elected a Deputy Leader. Although often referred to as the Deputy Leader of the Liberal Democrats, this post is actually only Deputy Leader of the Liberal Democrat parliamentary group in the House of Commons and not Deputy Leader of the Lib Dems as a whole.

Daisy Cooper was elected by her fellow MPs to the post of Deputy Leader following Ed Davey's election to the post of leader in September 2020.
