Ritchie Rock (Bulgarian: скала Ричи, romanized: skala Ritchie, IPA: [skɐˈla ˈrit͡ʃi]) 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.

[1] 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.
