The Knik Glacier (Dena'ina: Skitnu Łi'a) is an ice field located 50 miles (80 km) east of Anchorage, Alaska on the northern end of the Chugach Mountains.

The jökulhlaup occurred annually until it ceased in 1967 due to glacial recession, thought to be associated with the massive Good Friday earthquake of 1964.

Early pioneers were said to hold a yearly lottery, gambling on the exact date when the jökulhlaup would break and flood the Knik River Valley.

Knik Glacier was the setting for a scene in which Captain Kirk and Dr McCoy are rescued from the Klingon ice planet prison Rura Penthe.

The KRPUA is a legislatively designated area managed by the State of Alaska's Department of Natural Resources (DNR), Division of Mining, Land, and Water, Southcentral Regional Office.
