Rockabill () is a close pair of islands (Rock and Bill) in the western Irish Sea about 6 kilometres east-north-east of Skerries, County Dublin, Ireland. The two granite islands are separated by a channel about 20 metres wide. On the Rock there is a lighthouse, built 1855–1860 from granite and limestone and automated in 1989, and several walls and outbuildings.
==Environment== The walled areas of the Rock have enabled a build-up of soil and the establishment of vegetation, notably tree mallow (Malva arborea), which provides nesting cover for the birds. The Bill is smaller and has very little vegetation.
