The 1969 New York City mayoral election occurred on Tuesday, November 4, 1969, with incumbent Liberal Party Mayor John Lindsay elected to a second term. Lindsay defeated the Democratic candidate, New York City Comptroller Mario Procaccino, and the Republican candidate, state senator John Marchi.

Lindsay received 42.36% of the vote to Procaccino's 34.79%, a Liberal victory margin of 7.57%. Marchi finished a distant third with 22.69%.

In one of the most unusual primary seasons since the consolidation of greater New York, the incumbent Lindsay and former mayor Robert F. Wagner Jr. lost their respective Republican and Democratic primaries. Lindsay, defeated narrowly by state senator John J. Marchi of Staten Island for the Republican nomination, gained ballot access to the general election via the Liberal Party, which had co-nominated him in 1965. Procaccino won the Democratic primary by less than 33% of the vote against four other candidates: Wagner, Bronx Borough President Herman Badillo, Congressman James H. Scheuer, and author Norman Mailer, who ran on a platform proposing secession from the state of New York.
