The 1970 United States Senate election in New York was held on November 3, 1970, to elect New York's Class I Senator in its delegation. Representative Charles Goodell had been appointed by Governor Nelson Rockefeller to serve the remainder of Robert F. Kennedy's senatorial term, following Kennedy's assassination.

Goodell attempted to win election to a full term in the Senate with the Republican and Liberal nominations, but faced opposition from Democratic nominee Richard Ottinger and Conservative nominee James L. Buckley. Buckley was able to win with a plurality of the popular vote due to the left-wing vote being split between Ottinger and Goodell.

Buckley would serve in the Senate until his re-election bid was defeated by Daniel Patrick Moynihan in 1976. Buckley's victory in the 1970 election would remain the last time a third-party candidate won election to the Senate until Connecticut Senator Joe Lieberman won re-election with the Connecticut for Lieberman nomination in 2006, and the most recent occasion that a non-incumbent Senate candidate won on a third-party ballot line.
