South Yuyanq’ Ch’ex[1] (formerly "South Suicide Peak") is a 5,005-foot (1,526 m) mountain in the U.S. state of Alaska, located in Chugach State Park.

The peak is notable for its graceful pyramidal shape and symmetry with nearby North Yuyanq’ Ch’ex, and as the tallest mountain rising from the North side of Cook Inlet's Turnagain Arm.

South Yuyanq’ Ch’ex is located on the southern edge of Chugach State Park, in Alaska, and is positioned between North Yuyanq’ Ch’ex, Indianhouse Mountain, Rabbit Lake, and McHugh Peak.

Due to its location near Anchorage, Alaska and ease of access from multiple trailheads, South Yuyanq’ Ch’ex is a relatively popular climbing destination.

It is considered a non-technical, but rigorous, one-day climb when free of snow.
