Robert E. Grant (September 26, 1825 – July 17, 1888) was a Virginia farmer and dentist who represented Washington County for one term in the Virginia House of Delegates and later at the Virginia Secession Convention of 1861. During the American Civil War, he recruited a company of the 37th Virginia Infantry, but failed to win re-election as captain, and ultimately moved to Texas in 1872 and re-established his practice.
