The 2006 United States Senate election in New York was held on November 7, 2006. Incumbent Democratic U.S. Senator Hillary Clinton won re-election to a second term in office, by a more than two-to-one margin. Clinton was challenged by Republican John Spencer, the former mayor of Yonkers. Longtime political activist Howie Hawkins of the Green Party also ran a third-party campaign.

Howard Gresham Hawkins III is an American trade unionist, environmental activist, and perennial candidate from New York. A co-founder of the Green Party of the United States, Hawkins was the party's presidential nominee in the 2020 presidential election. His ideological platform includes enacting an eco-socialist version of the Green New Deal—which he first proposed in 2010—and building a viable, independent working-class political and social movement in opposition to the country's two major political parties, and capitalism in general.
