Mount Carru is an mountain summit located in western Okanogan County in Washington state. It is the 7th highest peak of the Okanogan Range, which is a sub-range of the North Cascades. The mountain is situated in the Pasayten Wilderness, on land administered by Okanogan National Forest. The nearest higher peak is Mount Lago, to the east, and Osceola Peak stands west. The mountain has a steep north face, but the south slope is covered in scree which allows a nontechnical climbing ascent. Precipitation runoff from Mount Carru drains north into Lease Creek which is a tributary of the Pasayten River, or south into Eureka Creek, which is part of the Methow River drainage basin.
