García II (1041/April 104322 March 1090), King of Galicia, was the youngest of the three sons and heirs of Ferdinand I, King of Castile and León, and Sancha of León, whose Leonese inheritance included the lands García would be given. García first appears in an 11 September 1064 settlement with Suero, Bishop of Mondoñedo, his father confirming the agreement.

In the 1065 division of his father's estates, García was given the County of Galicia, "elevated to the rank of kingdom", that extended south to the Mondego River in Portugal with the parias of the Taifa of Badajoz and Seville; his eldest brother Sancho received the Kingdom of Castile and the parias of the Taifa of Zaragoza. The second son and his father's favorite, Alfonso, fared best in this division, being given an expanded Kingdom of León that encroached on lands which historically had been Castilian and Galician. Garcia's Galician kingdom was the most troubled, including lands south of the Duero over which firm administrative control had only been reestablished with the recapture of Coimbra the year before Ferdinand's death. Further, Ferdinand had begun a process intended to weaken the old comital house to bring the nobles under more direct royal control, but not yet finalized at his death. Further, the bishops of Lugo and Santiago were competing for preeminence.
Fraternal war
Among García's first acts was to receive the forced surrender of nearly the entire holdings of prominent nobleman García Múñoz. He also initiated plans to reestablish bishoprics at Braga, Lamego and Tui, as further tools for asserting royal authority, but suffered a significant setback when in 1068 the long-serving Bishop of Santiago died, then his successor was murdered the next year, an act that can be seen as a direct challenge to the king who might have been viewed as acting in an overly energetic manner, and indicating a loss of royal authority in Galicia. García seems to have turned his attention to strengthening his control in the south. whom García defeated and killed at the Battle of Pedroso. This reunited the realm their father had divided, and García's independent kingdom of Galicia and Portugal ceased to exist.
