John Gallup (also Gallop, born 1619 in Dorset, England – died 1675 in South Kingstown, Rhode Island) was an early settler and militia captain in Southeastern Connecticut.
On September 4, 1633, the younger Gallup arrived in Boston in the Massachusetts Bay Colony aboard the Griffin with his mother, brothers, and sister Joan.
In one engagement off the coast of Block Island, the Gallups used their ship to ram another vessel that had been commandeered by Pequot warriors.
When New London County raised seventy men under Captain John Mason of Norwich, Connecticut, Gallup joined with him to lead their Mohegan allies.
While leading a successful charge on the Narragansett fort, Gallup was killed by a musket ball shot to the head.
In World War II, the Liberty ship SS John Gallup (Hull #951) was launched on March 3, 1943 and scrapped in 1963.
