LaMoure County is a county in the U.S. state of North Dakota. As of the 2020 census, the population was 4,093. Its county seat is LaMoure.

USS La Moure County (LST-1194) was the sixteenth of twenty Newport-class tank landing ship of the United States Navy (USN) which replaced the traditional bow door-design tank landing ships (LSTs). The second vessel named after a county in North Dakota, the LST was constructed by National Steel and Shipbuilding Company of San Diego, California. The vessel was launched and was commissioned into the USN in 1971. La Moure County alternated deployments in the Caribbean Sea with those to the Mediterranean Sea. During the Gulf War, La Moure County transported elements of the 4th Marine Expeditionary Brigade to the Persian Gulf. In 2000, the LST was taking part in a training exercise off Chile when the vessel ran aground. Considered beyond repair, La Moure County was decommissioned that year and towed out to sea in 2001 and sunk as a target ship.
