James W. Stephenson (1806–August 1838) was an American militia officer and politician from the state of Illinois. He was born in Virginia but spent most of his youth in Edwardsville, Illinois. In 1825 he was indicted for the murder of a family acquaintance, but never went to trial. Upon the outbreak of the Black Hawk War in 1832, Stephenson raised a company and saw combat, suffering severe wounds at the Battle of Waddams Grove.
