The New York School was a group of American artists, writers, poets, painters, dancers, and musicians active in the mid-20th century in New York City. They are often associated with the Abstract Expressionist movement, although many of them were initially opposed to or even hostile to Abstract Expressionism.

The New York School is sometimes referred to as the Second Generation of Abstract Expressionism, or the New York School of Abstract Expressionism, to distinguish them from the first generation, which included Jackson Pollock, Willem de Kooning, and other artists associated with the art movement. They were united by their rejection of traditionalism and their embrace of experimentation.
