The New York Sun is an American conservative news website and former newspaper based in Manhattan, New York. From 2009 to 2021 it operated as an online-only publisher of political and economic opinion pieces, as well as occasional arts content. Dovid Efune acquired the paper in November 2021, and it began full-time online publication in 2022.

The Sun was a New York newspaper published from 1833 until 1950. It was considered a serious paper, like the city's two more successful broadsheets, The New York Times and the New York Herald Tribune. The Sun was the first successful penny daily newspaper in the United States, and was for a time, the most successful newspaper in America.
