Rathdangan (Irish: Ráth an Daingin[2], meaning 'Ringfort of the Stronghold') is a village in County Wicklow, Ireland.

[3] Evidence of habitation is shown by a Bronze Age burial cist, a fort dating from at least the eight-century and a Norman moat at Killamoat.

A few years later, in 1668, Rathdangin is stated in the Hearth Money Roll of County Wicklow, followed by Radangin in the 1685 Hiberniæ Delineatio.

[13] A holy well, Tober Owen, or St. John's Well, is a short distance from the village on the left side of the road leading to the Glen of Imaal.

[15] In 1889 a question were asked in the House of Commons on the possibility of opening a post office but, while it had been considered, it was refused by the Postmaster General on the grounds there was insufficient mail to warrant the cost.

[12] Until the 1950s, the large flat circular stone, inside the bridge wall, was used to install iron bands on wooden cart wheels.
