mountain on the Dingle peninsula, County Kerry, Ireland. It is 3,127 feet (953 m) high. The mountains of the western part of the peninsula are formed of rock strata known to geologists as the Dingle beds, and north of the town of Dingle they form the Brandon range—a high craggy ridge, of which Brandon Mountain is the highest point—which ends in cliffs at Brandon Head. The cliffs have been much modified by landslides.
