Caleb Harris (August 9, 1739 - January 16, 1812) was an American surveyor. Born near Providence, Rhode Island, Harris came from a prominent Rhode Island family. He served as a captain in the Captain General's Cavaliers from July 24-31, 1778, which coincided with the Battle of Rhode Island. He also was 'appointed one of a committee to procure weapons and accoutrements' for the town in March 1776 and was appointed Inspector of Gunpowder in October 1776. He became a member of a committee to provide blankets to the troops in April 1777 and was appointed Commissioner to sign and number bills of public credit in July 1780. He served as the Town Clerk of Johnston, Rhode Island, for many years, and also served on the Town Council at several points during his lifetime. Harris was also a prominent landowner in Johnston and owned an estate of 200 acres. He married Margaret Westcott on October 11, 1760, with whom he had 13 children, only 4 of whom lived beyond the age of 20. In 1795 Harris helped compile a landmark map of Rhode Island, the first accurate map of the state. One of his sons, Hardin Harris (September 12, 1768 - March 20, 1808) helped Harris make his landmark map of Rhode Island.
