This is a list of deputy leaders of the Liberal Democrats, a 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 Liberal Democrats as a whole.

Following the 2015 General Election, the Liberal Democrat Members of Parliament did not elect a deputy leader. Alistair Carmichael served on the Liberal Democrat frontbench team as Shadow First Secretary of State from 28 October 2016 until Swinson's election. Tom Brake served as Chief Whip of the Liberal Democrats in the House of Commons during is period. After the 2017 General Election, MP Jo Swinson stood for the deputy leadership and was elected unopposed.
