Isaac Roberts Hawkins (May 16, 1818 - August 12, 1880) was a politician and soldier. A lawyer by profession, Hawkins served during the Mexican War, and was part of a peace delegation from Tennessee, which unsuccessfully sought to diffuse the pending Civil War in 1861. He joined the United States Army in 1862. In March 1864, he and his regiment was captured at Union City, Tennessee by Confederate Colonel William Duckworth, after Duckworth tricked Hawkins into believing he face a much larger Confederate force, much to the disgust of the Union officers.
