Troughton Rocks (Bulgarian: скали Трутън, romanizedskali Troughton, IPA: [skɐˈli ˈtrutən]) are the group of rocks off the northwest extremity of Snow Island in the South Shetland Islands, Antarctica lying in an aquatory of 27 ha that is 315 m long in east-west direction and 120 m wide. The vicinity was visited by early 19th century sealers.

The feature is named after Edward Troughton (1753-1835), a British instrument maker who improved the theodolite design; in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
