The eastern cougar or eastern puma (Puma concolor couguar) is a subspecies designation proposed in 1946 for cougar populations in eastern North America. The subspecies as described in 1946 was declared extinct by the U.S. Fish and Wildlife Service in 2011. However, the 1946 taxonomy is now in question. The Canadian Wildlife Service has taken no position on the taxonomy. Cougars are currently common in western North America and may be expanding their range. Individuals are occasionally seen as vagrants in eastern North America.
