Captain Lazarus Stewart (July 4, 1734 – July 3, 1778) was an 18th-century Pennsylvanian frontiersman and member of the Paxton Rangers.
He is suspected of being a member of the "Paxton Boys" – a group of Scots-Irish militants who massacred the Conestoga Indians in 1763 – and was a prominent commander on the Yankee (i.e.
Connecticut) side in the Pennamite Wars.
He met his death in battle with the Loyalists and Iroquois at the Wyoming Massacre, in an attack precipitated by his own rashness.
