Benbulbin,  sometimes spelt Ben Bulben or Benbulben (from the Irish: Binn Ghulbain), is a large rock formation in County Sligo, Ireland. It is part of the Dartry Mountains, in an area sometimes called "Yeats Country". Benbulbin is a protected site, designated as a County Geological Site by Sligo County Council.

Benbulbin was formed during the ice age, when Ireland was under glaciers. Originally it was a large ridge. The moving glaciers shaped it into its present distinct formation. Benbulbin, and the Dartry Range, is composed of limestones on top of mudstones. These rocks formed in the area approximately 320 million years ago. Uppermost in the limestone layer is a thicker, harder limestone called the Dartry Limestone Formation. Below this is a thinner transitional limestone formation – the Glencar Limestone Formation. Further down, the lower slopes consist of shaly mudstone known as the Benbulben Shale Formation. Scree deposits are found near the base.

Fossils exist throughout the layers of the mountains. All layers have many fossilised sea shells. The shale layer also holds some corals. Barytes was mined at Glencarbury near Benbulbin in the Dartry range between 1894 and 1979.
