Rathmolyon (/ræθmɒˈlaɪn/; Irish: Ráth Moliain, meaning 'ringfort of the plain of St. Liadhain'[2]) is a village in the southern portion of County Meath, Ireland, situated 8 km south of Trim.

Rathmolyon serves as a service centre for the surrounding rural area.

[2] Bus Éireann route 115A provides a commuter link from Rathmolyon to Dublin via Summerhill and Dunboyne with one journey in the morning and an evening journey back every day except Sunday.

A number of buildings in the village date from the Georgian and Victorian periods.

During the late 19th century, the area played a role in the development of the Two by Twos and Cooneyite movement,[4] the only religion known to have had its origin in Ireland.
