Northwest Indian War Colonel Jacob Kingsbury (1756–1837) was a career officer in the United States Army.

[1] He was born in the West Farms Society of Norwich, Connecticut, on July 6, 1756, to Nathaniel and Sarah Hill Kingsbury.

He served in the ill-fated campaigns of Colonel Josiah Harmar in 1790 and General Arthur St. Clair in 1791 against the Miami Tribe in what is modern-day Ohio.

On January 10 and 11, 1791, Kingsbury distinguished himself at the Siege of Dunlap's Station, where he led a detachment of only 12 soldiers, along with a few settlers, in defending a small outpost against a far superior force of Native Americans.

Kingsbury was succeeded in command of the district in July 1814 by Brigadier General Thomas Humphrey Cushing.

He married Sally Palmer Ellis (1778–1857), by whom he had five sons and three daughters: Reflecting his military service, Kingsbury's personal papers are located at a number of historical archives associated with locations he served at including the Missouri Historical Society Archives, the Detroit Public Library, and the Library of Congress.
