The 2020 Liberal Democrats leadership election was held in August 2020, after Jo Swinson, the previous leader of the Liberal Democrats, lost her seat in the 2019 general election. It was initially set to be held in July 2020, but due to the COVID-19 pandemic it was delayed by six weeks, having been at first postponed until May 2021.

The Liberal Democrat Conference, also known inside the party as the Liberal Democrat Federal Conference, is a twice-per-year political conference of the British Liberal Democrats, the third-largest political party in the UK by the number of votes cast. The Conference is typically held over three days in Spring and four in Autumn, during the party conference season, at a variety of venues. It culminates in a speech by the party's Leader.
