New Abstraction (Post-Painterly Abstraction) is a term created by art critic Clement Greenberg as the title for an exhibition he curated for the Los Angeles County Museum of Art in 1964, which was subsequently shown at the Walker Art Center and the Art Gallery of Toronto.
Greenberg had noted that there was a new movement in painting that derived from the abstract expressionism of the 1940s and 1950s but favoured "openness or clarity" as opposed to the dense painterly surfaces of that style of painting.
The 31 artists in the exhibition included Walter Darby Bannard, Jack Bush, Gene Davis, Thomas Downing, Friedel Dzubas, Paul Feeley, John Ferren, Sam Francis, Helen Frankenthaler, Sam Gilliam, Al Held, Ellsworth Kelly, Nicholas Krushenick, Alexander Liberman, Morris Louis, Arthur Fortescue McKay, Howard Mehring, Kenneth Noland, Jules Olitski, Ray Parker, David Simpson, Albert Stadler, Frank Stella, Mason Wells, Emerson Woelffer, and a number of other American and Canadian artists who were becoming well known in the 1960s.
