Philip Leslie Hale (1865–1931) was an American Impressionist artist, writer and teacher.
Hale was born in Boston, the son of prominent minister Edward Everett Hale, the brother of artist Ellen Day Hale, and was related to Nathan Hale and Harriet Beecher Stowe. He studied at the School of the Museum of Fine Arts in Boston under Edmund Tarbell, and with Kenyon Cox and J. Alden Weir at the Art Students League of New York. Beginning in 1877 he studied in Paris for five years, and during the summers painted at Giverny, where he was influenced by the palette and brushwork of Claude Monet. In the 1890s he painted his most experimental works, which evidenced an interest in Neoimpressionism and Symbolism.
Hale returned to Boston in 1893. He married fellow artist Lilian Westcott Hale in 1902, and they rented adjoining studios in Boston. Hale taught at the Museum School in Boston, as well as the Metropolitan Museum of Art and the Pennsylvania Academy of the Fine Arts. He wrote art criticism and published Jan Vermeer of Delft in 1913, the first monograph on the artist published in the United States.
