2021 North Northamptonshire Council election

The 2021 North Northamptonshire Council election took place alongside nationwide local elections. The election was originally due to take place in May 2020, but was postponed due to the COVID-19 pandemic.

It was the inaugural election for the unitary authority, which was created one month before in April 2021, after the merger of the four existing non-metropolitan districts of Corby, East Northamptonshire, Kettering, and Wellingborough. North Northamptonshire absorbed the functions of these districts, plus those of the abolished Northamptonshire County Council. All 26 wards elect 3 councillors each, resulting in 78 councillors being elected and 40 seats being required for a majority.
