Donald Sutherland was a Scottish-born New Zealand explorer, active in the late 19th century. Born in Wick, he served as a soldier in the Expedition of the Thousand, led by Giuseppe Garibaldi, in the Italian unification wars. Soon afterwards he travelled to New Zealand where he prospected for gold in Otago. He later joined the New Zealand military and fought in a number of engagements of the New Zealand Wars. In 1877, he settled in Milford Sound and lived as a hermit for a number of years, exploring the region. He later married and, with his wife, ran an accommodation facility for the increasing number of tourists visiting Milford Sound until his death in October 1919. The Sutherland Falls, located near Milford Sound and the highest waterfall in New Zealand, is named for him.

Mitre Peak is a mountain in the South Island of New Zealand, located on the shore of Milford Sound.
