Succor Creek is a 69.4 mi tributary of the Snake River in the U.S. states of Idaho and Oregon. The creek begins in the Owyhee Mountains in Owyhee County, Idaho. After flowing for about 23 mi in Idaho, Succor Creek enters Malheur County, Oregon, where it flows for 39 mi before re-entering Idaho for its final 5 mi. It joins the Snake near Homedale, about 413 river miles (665 km) from the larger river's confluence with the Columbia River. Succor Creek State Natural Area is 30 mi south of Nyssa along an unpaved road off Oregon Route 201. It has only primitive camping with no potable water. The canyon in which the natural area is located is known for fossils, geologic formations, and thundereggs, the Oregon state rock.
