Castle Creek is a tributary of the North Fork Toutle River on the flank of Mount St. Helens in Washington state. It rises about two miles (three kilometers) northwest of the crater rim (46°13′01″N 122°14′22″W / 46.21690°N 122.23934°W) and flows generally to the northwest. The outflow of Castle Lake joins the creek at the lake's north end (46°15′29″N 122°16′19″W / 46.258°N 122.272°W) after traveling a few hundred meters on the South Fork Castle Creek. It joins the North Fork Toutle River at 46°16′59″N 122°17′37″W / 46.28302°N 122.29359°W, elevation 2,200 feet.
Castle Lake was created by an avalanche subsequent to the May 18, 1980 eruption of Mount St. Helens which blocked South Fork Castle Creek. Pre-1980 maps show this area as "Castle Creek Marsh".
