Cape Brewster (Danish: Kap Brewster; Greenlandic: Kangikajik, meaning 'the bad cape') is a headland in the Greenland Sea, east Greenland, Sermersooq municipality.

This headland was named Cape Brewster by William Scoresby (1789 – 1857) in 1822 to honour his friend, inventor David Brewster (1781–1868).

[1] Cape Brewster is the easternmost point of the jagged and mountainous Savoia Peninsula and the northernmost point of the Blosseville Coast.

[2] It is located at the end of the southern side of the mouth of the Scoresby Sound, opposite Cape Tobin (Uunarteq).

[3] The cape lies in the desolate and impressive area of the southern shore of the sound with steep dark basalt walls rising between 1,000 and 2,000 m (3,280-6,560 ft).
