Klamath plum, also called Oregon plum, or Sierra plum (Prunus subcordata) is a member of the genus Prunus (plum, cherry, and other stone fruit), native to the west coast of the United States in California and southern Oregon. It grows in forests, most often at low elevation near the coast, but it is also in the Sierra Nevada and Cascades; it grows at altitudes of 100–1,900 m.
