George Winter (June 10, 1809 – February 1, 1876) was an English-born landscape and portrait artist who immigrated to the United States in 1830 and became an American citizen in northern Indiana's Wabash River valley. Winter was one of Indiana's first professional artists. In addition, he is considered the state's most significant painter of the first half of the nineteenth century. Winter is especially noted for his sketches, watercolors, and oil portraits that provide a visual record of the Potawatomi and Miami people in northern Indiana from 1837 to the 1840s, as well as other figures drawn from his firsthand observations on the American frontier.
