St. Assam's is the name of two historic churches in the village of Raheny, Dublin, one a ruin in the middle of the village, one the structurally sound but no longer primary church built for the local Roman Catholic community of the area after the revival of religious rights. Both buildings lie within the area of the ráth which gave the village and district its name, and which was perhaps 110 m across.

Raheny is a northern suburb of Dublin, Ireland, halfway from the city centre to Howth. It is centred on a historic settlement, first documented in 570 AD. The district shares Dublin's two largest municipal parks, Saint Anne's Park and Bull Island with its 4.5 km beach, with neighbouring Clontarf, and is crossed by several small watercourses.
