Musheramore (Irish: Muisire Mór, 'big Mushera') is a mountain with a height of 643 metres (2,110 ft) in County Cork, Ireland.

It is the highest of the Boggeragh Mountains.

[2] The neighbouring hill is Musherabeg (Muisire Beag, 'little Mushera'), with a height of 499 metres (1,637 ft).

[4] 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.

[5] 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.
