2021 North Hertfordshire District Council election

The 2021 North Hertfordshire District Council election took place on 6 May 2021 to elect 17 of the 49 members of North Hertfordshire District Council in England. This was on the same day as other local elections around the country. This election had originally been due to take place in May 2020, but was postponed due to the COVID-19 pandemic.

The council remained under no overall control, with a Labour and Liberal Democrat coalition continuing to run the council. Martin Stears-Handscomb, leader of the Labour group and leader of the council prior to the election, lost his seat at this election; he had chosen to contest Letchworth South East rather than the Hitchin Oughton seat he had previously held, which put him directly challenging the Conservative leader, David Levett, who retained the seat. Elizabeth Dennis-Harburg was appointed new leader of the Labour group and leader of the council after the election, with the Liberal Democrat leader, Paul Clark, continuing to serve as deputy leader of the council.
