Seefin Passage Tomb (Irish:Tuama Pasáiste Shuí Finn) is an empty passage grave and National Monument located atop Seefin Hill, County Wicklow, Ireland.

Seefin Passage Tomb is located atop Seefin in the Wicklow Mountains, just south of Kilbride Army Camp. Nearby Seefingan and Seahan mountains also have cairns atop them.

The tomb was built circa 3300 BC, during Ireland's Neolithic. It was excavated by R. A. Stewart Macalister in 1931, but no artefacts or human remains were found, suggesting that no-one was ever buried there, or that the remains were later removed.

The tomb is a stone cairn, 24 m (79 ft) in diameter and 3 m (9.8 ft) high. There are large kerb stones around the base of the tomb and the tomb has a passageway 7 m (23 ft) long, which opens into a chamber with five compartments. There are some carved decorations in lozenge shape, carved lines and quartz.
