Ramiro II (c. 900–1 January 951), son of Ordoño II, is a King of León from 931 until his death.

Initially titular king only of a lesser part of the kingdom, he gains the crown of León (and with it, Galicia) after supplanting his brother Alfonso IV and cousin Alfonso Fróilaz in 931.

The scant Anales castellanos primeros are a primary source for his reign.
