The Pole of Inaccessibility research station is a defunct Soviet research station in Kemp Land, Antarctica, at the southern pole of inaccessibility as defined in 1958 when the station was established. Later definitions give other locations that are all relatively close to this point. It performed meteorological observations from 14 to 26 December 1958. The Pole of Inaccessibility has the world's coldest year-round average temperature of −58.2 °C (−72.8 °F).
