The 2021 Calderdale Metropolitan Borough Council election took place on 6 May 2021 to elect members of Calderdale Metropolitan Borough Council in England. This was on the same day as other local elections. One-third of the seats were up for election. The election was originally scheduled for 7 May 2020, alongside the later cancelled 2020 West Yorkshire Police and Crime Commissioner election and other local elections across the UK, but was delayed for a year due to the COVID-19 pandemic.
