Arrhichion of Phigalia was a champion pankratiast in the ancient Olympic Games. He died while successfully defending his championship in the pankration at the 54th Olympiad. Arrhichion has been described as "the most famous of all pankratiasts".

Phigalia or Phigaleia or Phigalea, also known as Phialia, was an ancient Greek city in the south-west corner of ancient Arcadia, in the region of ancient Parrhasia close to the frontiers of Messenia, and upon the right bank of the Neda, about halfway between the sources and the mouth of this river. It is also the present name of a nearby modern village, known up to the early 20th century as Pavlitsa (Παύλιτσα). In modern geography it is located in southeastern Elis. It is situated on an elevated rocky site, among some of the highest mountains in the Peloponnese, the most conspicuous being Mt Cotylium and Mt Elaeum; the identification of the latter is uncertain.
