Amelia C. Van Buren (c. 1856 – 1942) was an American photographer who was best known for being the subject of Thomas Eakins's c. 1891 painting Miss Amelia Van Buren.
Van Buren was born in Detroit, Michigan. Both her parents died sometime prior to 1884, when she began attending the Pennsylvania Academy of the Fine Arts. She had already been exhibiting her artwork in Detroit for at least four years prior to attending the Academy.
Her talent soon led Eakins to tutor her personally, including controversial lessons using nude models, male and female. In 1885–86, several of Eakins's former art students (including Thomas Pollock Anshutz and Colin Campbell Cooper) conspired to have Eakins fired from the Pennsylvania Academy of Fine Arts. They approached the Academy's Committee on Instruction, and made numerous charges against Eakins. They alleged that Eakins had used female students, including Van Buren, as nude models. Another highly inflammatory charge was that Van Buren had asked Eakins a question regarding pelvic movements, which Eakins answered by removing his pants and demonstrating the movements. He later insisted that the episode was completely professional in nature. The committee left Eakins under the impression that the charges had been filed by Van Buren, who had moved to Detroit to recover from neurasthenia. That, however, was not the case, as she greatly respected Eakins and in years to come would defend him at every opportunity, as well as express pride in owning pieces of his artwork.
After recovering, Van Buren returned to Philadelphia, where she continued in her studies under Eakins at the Art Students' League of Philadelphia. Van Buren and Eakins stayed in close contact for a number of years afterward. Three or four years after his dismissal, Eakins painted Van Buren in Miss Amelia Van Buren.
