Waldseemüller Rock (Bulgarian: скала Валдзеемюлер, romanized: skala Waldseemüller, IPA: [skɐˈla ˈvaldzɛɛmʲulɛr]) is the rock off the south extremity of Snow Island in the South Shetland Islands, Antarctica; it is 136 m long in the west-east direction and 53 m wide, with a surface area of 0.48 ha. The vicinity was visited by early 19th-century sealers.
The feature is named after Martin Waldseemüller (circa 1470-1520), a German cartographer and topographer who created an early forerunner of the theodolite, in association with other names in the area deriving from the early development or use of geodetic instruments and methods.
