Dúnhere was a captain of riders and the Lord of Harrowdale in the White Mountains. During the War of the Ring, Dúnhere did not accompany Gandalf and Erkenbrand to the Battle of the Hornburg; instead, they sent him to oversee the muster of the Rohirrim in his native Harrowdale. Several days later, he met King Théoden when he arrived at the Harrowdale. He was also present in the King's pavilion at Dunharrow in a council concerning the Muster of Rohan. At the Battle of the Pelennor Fields, Dúnhere was slain along with many heroes. He was remembered in the Song of the Mounds of Mundburg.
