Una Peaks,[1][2] formerly known as Cape Renard Towers,[3] are two towers of basalt, each topped by a cap of ice, guarding the northern entrance to the Lemaire Channel on the Antarctic Peninsula.

With the highest summit at 747 metres (2,451 ft),[4] The formation has been long colloquially known as "Una's Tits".

[1] The peaks appear on a British Antarctic Territory stamp although they are not identified as such.

[5] Una Spivey was the name of a secretary in the governor's office in Stanley, Falkland Islands[1] who was working for what is now the British Antarctic Survey.

[6] The tallest tower has only been summited once; this was by a German team in 1999 [4] (Kurt Albert, Stefan Glowacz, Hans Martin Götz, Gerhard Heidorn, Holger Heuber and Jürgen Knappe).
