Raheny (Ráth Eanaigh in Irish) 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 CE (Mervyn Archdall). 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.
