Przewalski's toadhead agama (Phrynocephalus przewalskii), also known as Tsarewsky's toadhead agama, or Steindachner's toadhead agama, is a species of agamid lizard found in China and Mongolia. This species was named after Nikolay Przhevalsky, a Russian Imperial geographer and explorer of Central and East Asia.
