The Chugai' Pictograph Site is a prehistoric rock art site on the island of Rota in the Northern Mariana Islands. The rock art is located in a limestone cave on the southeastern side of the island, in the I'Chenchon Bird Sanctuary. It consists of a large panel, 185 feet (56 m) in length, of about 90 painted drawings, believed to be of late pre-contact origin. The site is accessed via a trail cut by the Japanese during the South Pacific Mandate period. The site was listed on the National Register of Historic Places in 1998.
