Manx Peak, mountain summit in Jasper National Park, Alberta, Canada

Manx Peak is a 3,044-metre summit in the Trident Range of Jasper National Park, Alberta. Circus Valley lies at its south side, and its northeast face rises above the head of Whistlers Creek valley. The nearest higher peak is Mount Estella, 1.8 km to the southwest, and Terminal Mountain stands 2.0 km to the east.

The peak was named in 1916 by Morrison P. Bridgland, a Dominion Land Surveyor, who saw resemblance between its contours and the triskelion symbol of the Isle of Man. This naming choice reflected the surveyor's observation of the mountain's distinctive three-part outline.

Morrison P. Bridgland, a Dominion Land Surveyor, chose the name in 1916 because the mountain's contour lines resemble the triskelion, the three-legged symbol on the Isle of Man flag. The name was officially adopted in 1951 by the Geographical Names Board of Canada.

The first ascent was made in 1919 by R.T. Chamberlin and B. Herzberg, and the summit stands at 3,044 metres. Under the Köppen classification the peak lies in a subarctic zone, with winter temperatures falling below −20 °C and wind chill below −30 °C. Runoff from the mountain drains into tributaries of the Athabasca River. Jasper town lies 14 km to the north-northeast.

The mountain was named after the three-pronged symbol on the Isle of Man flag because its overall outline resembles this historic emblem. The visual connection between the mountain's shape and this heraldic symbol can be observed from various vantage points.
