Ritchie Rock ({{langx|bg|скала Ричи|skala Ritchie}}, {{IPA|bg|skɐˈla ˈrit͡ʃi|IPA}}) is the conspicuous rock off the southwest coast of Snow Island in the South Shetland Islands, Antarctica extending 80 m in south–north direction and 73 m in west–east direction, with a surface area of 0.17 ha. The vicinity was visited by early 19th century sealers.L. Ivanov.

The feature is named after Edward Samuel Ritchie (1814–1895), an American inventor and physicist who created a waterborne version of the theodolite used in harbour surveys; in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
