Seefingan often spelt Seafingan (Irish: Suí Fingain meaning Fingan's Seat) is a mountain that straddles two county boundaries from its summit in Wicklow eastwards down into South Dublin, in Ireland.

[1] It stands at the junction of three ridges, Corrig to the north, Seefin to the southwest and Kippure to the east, and straddles the border between County Wicklow and South Dublin.

There is not a cairn on the summit, but there is a notice warning walkers of Kilbride Camp and the nearby military firing range.

There are extensive views to the mountains of western Wicklow, Mullaghcleevaun and Poulaphouca Reservoir, the prominent communication masts on the top of Kippure and across the city of Dublin towards Howth.

A few hundred yards west of the summit lies a large megalithic cairn, which probably marks the site of a collapsed passage tomb.
