Joseph Bowman (c. 1752 – c. 14 August 1779) was a Virginia militia officer during the American Revolutionary War. He was second-in-command during George Rogers Clark's famous campaign to capture the Illinois country, in which Clark and his men seized the British-controlled towns of Kaskaskia, Vincennes, and others. Bowman was injured in an accidental gunpowder explosion after the campaign, and subsequently died of his wounds. He was the only American officer killed during the Illinois campaign.
