Dwight William Tryon (August 13, 1849 – July 1, 1925) was an American landscape painter in the late 19th and early 20th centuries.

His work was influenced by James McNeill Whistler, and he is best known for his landscapes and seascapes painted in a tonalist style.

As a young man Tryon took a job at a prominent Hartford bookstore and studied art instruction manuals from the store shelves.

Impressionism was blossoming in France all around Tryon, but he was not swayed by the new style and remained comfortably within the realm of the Barbizon school.

Though he would continue to spend each winter in New York City, South Dartmouth became Tryon's home for the rest of his life.

The coastal area appealed to Tryon's aesthetic sensibilities and allowed him to indulge in fishing, his favorite pastime.

He is described in the "Fine Art Catalogue" which is copyrighted by Theodore Cooley as follows: "William Tryon is an American landscape painter whose pictures are greatly sought for their delicacy of coloring and refinement of feeling.

A pupil of Daubdigny, he is, like that artist, a painter of country life - the idyllic rusticity of apple trees in bloom, of waving cornfields, of shining valleys and streams rippling gently to the sea.
