Brevet Brigadier-General James Miller (April 25, 1776 – July 7, 1851) was a senior officer of the United States Army who commanded infantry in the Canadian Theater of the War of 1812. After the war, he served as the first governor of Arkansas Territory from 1819 to 1824. He also served as the superintendent of Indian affairs for the territory. It was during his term as governor, and partly due to his influence, that the territory's capital was moved from Arkansas Post to Little Rock.
