Musheramore (, 'big Mushera') is a mountain with a height of 643 m in County Cork, Ireland. It is the highest of the Boggeragh Mountains. The neighbouring hill is Musherabeg (Muisire Beag, 'little Mushera'), with a height of 499 m. Historically the mountain was called Knock Muskery, from Cnoc Múscraighe meaning "hill of the Múscraige", a Gaelic tribe who gave their name to the barony of Muskerry. There are two holy wells on the mountain: one near the summit for sick animals, and one on its northern slopes for humans (St John's Well), where mass was traditionally held on midsummer.
