Silver–Russell syndrome, also called Silver–Russell dwarfism, is a rare congenital growth disorder. In the United States it is usually referred to as Russell–Silver syndrome, and Silver–Russell syndrome elsewhere. It is one of 200 types of dwarfism and one of five types of primordial dwarfism.

Silver–Russell syndrome occurs in approximately one out of every 50,000 to 100,000 births. Males and females seem to be affected with equal frequency.
