Mitre Peak, Mountain summit in Milford Sound, New Zealand

Mitre Peak (Māori: Rahotu) is a mountain on the shore of Milford Sound in Fiordland National Park, southwestern South Island, New Zealand. It rises to 1,690 metres (5,560 ft) with almost sheer drops to the water. The peak is actually a closely grouped set of five peaks, though from most accessible viewpoints it appears as a single point.

Captain John Lort Stokes of HMS Acheron named the peak in 1851 for its resemblance to a bishop's mitre. The first attempt to climb it came in 1883 from artist Samuel Horatio Moreton and settler Donald Sutherland, but bad weather stopped them. On 13 March 1911 James Robert Dennistoun reached the summit alone after Joe Beaglehole turned back near the top.

The Māori name Rahotu is recorded for the peak, while the English name comes from Captain John Lort Stokes of HMS Acheron, who in 1851 saw a resemblance to a bishop's mitre. The mountain has appeared on six New Zealand Post stamps since 1895, the last a 40-cent issue on 2 October 1995, and painters have used it as a subject, among them John Barr Clark Hoyte in the 1870s.

Mitre Peak is not a walk-up summit: the six climbing routes are technical, and most parties begin with a boat across Milford Sound to Sinbad Bay. The only road into Milford Sound is State Highway 94. From the water and the Milford Sound wharf the peak is seen from below, as a five-pointed massif rather than a single cone.

It actually consists of five separate peaks that align perfectly when viewed from Milford Sound, creating the illusion of a single pointed summit. This optical effect depends on where you are positioned when looking at it from the water.
