Gárulf was a rider of the Eored during the War of the Ring. He was killed in Fangorn Forest when Éomer and his men attacked the Uruk-hai. His steed Hasufel was later given to Aragorn by Eomer, as a compensation for the presumed deaths of Merry and Pippin.
Gárulf is Old English for "spear-wolf". It was a name of a jutish warrior in the Finnsburg Fragment.
