The 2021 New York City Council election were held on November 2, 2021. The primary elections were held on June 22, 2021. There were several special elections for seats vacated in 2020 and early 2021; these special elections were the first to use ranked-choice voting in city council elections after it was approved by a ballot question in 2019. Due to redistricting after the 2020 Census, candidates also ran for two-year terms instead of four-year terms for the first time, stemming from the New York City Charter overhaul in 1989. Four-year terms will resume in the 2025 election after another two-year election in 2023.
