SS George Calvert was a Liberty ship built in the United States during World War II. She was named after George Calvert, an English politician and colonizer. Calvert took an interest in the British colonization of the Americas, becoming the proprietor of the Province of Avalon, the first sustained English settlement on the southeastern peninsula on the island of Newfoundland. He later sought a new royal charter to settle the region, which would become the state of Maryland.
