Elections for members of the New York City Council were held in 2013. Primary elections were held on September 10, 2013, for all 51 districts of the city council. Many incumbents are termed out of office, while others were defeated in the primary, resulting in the largest turnover of council members since 2001, when 36 new members were nominated and elected to office in the council. Those who won their primaries without another contending party in the same district are considered the effective winner of the seat outright.
