Folca was the thirteenth King of Rohan and the fourth of the second line. He was the son of Walda.

Folca was a great hunter but would only use his talents to hunt Orcs, as long as they remained in Rohan. After all of the Orcs were destroyed, he went to the Firienwood to hunt the great Boar of Everholt. He slew the beast but died himself from the tusk-wounds he received.

He was succeeded by his son Folcwine.
