Wilson Cary Swann (1806 – March 21, 1876) was an American physician, philanthropist, and social reformer. Born in present-day Alexandria, Virginia, he moved to Philadelphia in 1847, and spent the rest of his life there. Swann held around 40 slaves, whom he freed shortly after his marriage in 1847.
Swann had leadership roles in several philanthropic organizations in Philadelphia, including the Society for the Prevention of Cruelty to Animals and the Philadelphia Fountain Society, which financed the construction of numerous drinking fountains in the city. He also maintained a substantial art collection.
