The Shehy Mountains (Cnoic na Seithe in Irish, meaning "Hills of the animal hides") are a range of low mountains situated on the border between County Cork and County Kerry, in Ireland.

The River Lee rises in Coomroe, a small valley at the eastern end of the range, before flowing eastwards towards Cork Harbour, where it enters the sea.

The Shehy Mountains are mostly covered with peat bogs and coarse grassland, but there are also some small conifer plantations scattered around the area.

Numerous Neolithic megalithic monuments are found in the foothills and valleys, as well as ringforts, fulachta fia and later antiquities.

One of the most historic sites in the Shehy mountains is Gougane Barra in the Coomroe valley, where Saint Finbarr established a hermitage in the 6th century.
