The Conservative Party of New York State is an American political party founded in 1962 following conservative dissatisfaction with the Republican Party in New York. Running on the Conservative Party line, James L. Buckley won election to the U.S. Senate in 1970 and served for one term. Since 2010, the party has held "Row C" on New York ballots—the third-place ballot position, directly below the Democratic and Republican parties—because it received the third-highest number of votes of any political party in the 2010, 2014 and 2018 New York gubernatorial elections. The party is known for its strategy of attempting to influence the Republican Party in a more conservative direction.

James Lane Buckley was an American politician and judge who served in the United States Senate as a member of the Conservative Party of New York State in the Republican caucus from 1971 to 1977 and additionally held multiple positions within the Reagan administration. He was also the Republican nominee in the 1980 Connecticut Senate race, but he was defeated by Democrat Chris Dodd.
