Arcadia is a c.1883 painting by the American painter Thomas Eakins.

It is part of the collection of the Metropolitan Museum of Art, in New York.

In the early 1880s, Eakins, instructor in painting at the Pennsylvania Academy of the Fine Arts, began to photograph models dressed in classical garb or nude and posed in vaguely classical poses.

[2] Some of the photographs were used as studies for subsequent works, including those of nude young men swimming and relaxing on the shore of Dove Lake for the painting The Swimming Hole (1884–85).

Eakins's models for Arcadia were his former student and soon-to-be wife, Susan Macdowell, his teaching assistant at PAFA, J. Laurie Wallace, and his six-year-old nephew Ben Crowell (son of his sister Fanny).
