Friesland Ridge (Hrebet Frisland \'hre-bet 'fris-land\) is a ridge on Livingston Island in the South Shetlands, part of the Tangra Mountains. The summit, Mount Friesland, which rises to 1,700 metres (5,600 ft), is the northwesternmost of the ridge's six main peaks. Its elevation was estimated at 1,684 metres (5,525 ft) by a 1995/96 Bulgarian survey;[1] the present figure was produced by a 2003 Australian GPS survey,[2][3] and closely matched (as 1,702 metres (5,584 ft)) by the Bulgarian survey Tangra 2004/05.

The local ice relief is subject to changes, causing variations in the mountain peaks’ elevation. According to a Bulgarian GPS survey by D. Boyanov and N. Petkov the elevation of Mt. Friesland was 1,693 metres (5,554 ft) in December 2016, making the peak lower than the adjacent St. Boris Peak (the latter's northernmost ice formation ‘The Synagogue’ rising to 1,699 metres (5,574 ft)) at that time.[4]

First ascent of the summit Mount Friesland by the Catalans Francesc Sàbat and Jorge Enrique from Juan Carlos I Base on 30 December 1991.

The feature takes its name from Mount Friesland.
