Ezo (disambiguation)

Ezo can refer to:

• Ezo (蝦夷, also spelled Yezo or Yeso) is a Japanese name which historically referred to the lands to the north of the island nation
• The major northern Japanese island of Hokkaidō (until 1869).
• The short-lived Republic of Ezo on Hokkaidō.
• The lands around the Sea of Okhotsk (historical usage).
• The Ainu people, and more vaguely, any peoples with whom the Japanese came into contact to their north.
• The Red Ezo, a name historically used by the Japanese for the Russians of the Far East, normally Siberian Cossacks, on account of their supposedly red hair. Once the Japanese had clearly identified these people as Russians (in Japanese: Oroshiya), of whom they were already aware through Dutch traders, the term Red Ezo fell into disuse.

This term can also refer to:
