Fruela II (Froila II) (c. 875–July 925) is the King of Asturias from the death of his father, Alfonso III of Asturias, in 910 to his own death.

When his father dies, the kingdom is divided, with the third son, Fruela, taking the original portion (Asturias); the second, Ordoño, taking Galicia; and the eldest, García, taking León.

As king of Asturias, he has the job of consolidating the region later called Castile and keeping its counts in check.
