Edmond Thomas Quinn (December 20, 1868 – September 9, 1929) was an American sculptor active from the Gilded Age to the Jazz Age, with work in the collections of the Metropolitan Museum of Art, National Portrait Gallery, Whitney Museum of American Art, and the National Gallery of Ireland.

Among his sitters were Playwright Eugene O'Neill, Painter Leon Kroll, and architect Cass Gilbert.

Following Eakins's February 1886 forced-resignation from PAFA, Quinn followed him to the Art Students League of Philadelphia, and later became that short-lived school's curator.

He won a silver medal for his bronze sculpture of model Audrey Munson at the Panama-Pacific Exposition, San Francisco, 1915.

His portrait busts include Franklin Hooper, Sylvester Malone, Edwin Markham, Vicente Blasco Ibáñez, Padraic Colum and Eugene O'Neill.
