2021 London Assembly election

The 2021 London Assembly election was held on 6 May 2021 to elect the members of the London Assembly, alongside the 2021 London mayoral election. The mayoral and Assembly elections were originally to be held on 7 May 2020, but on 13 March 2020 it was announced the election would be postponed until 2021 due to the COVID-19 pandemic. It was the sixth election since the Assembly was established in 2000. Due to the previous term being extended to 5 years, those elected would only serve a three-year term until the next election in 2024. The election was held on the same day in 2021 as other elections in the UK; the UK local elections, Scottish Parliament election, and Welsh Senedd election.

Five parties had featured in the fifth Assembly: London Labour led by Len Duvall; London Conservatives led by Gareth Bacon and latterly Susan Hall; London Greens led by Caroline Russell; UKIP London represented by David Kurten (as part of the Brexit Alliance group led by its former leader Peter Whittle); and the London Liberal Democrats led by Caroline Pidgeon. This fell to four parties after the election, as UKIP lost both its seats.
