Magilligan (from Irish Ard Mhic Giollagáin, meaning 'Magilligan's height'[1]) is a peninsula that lies in the northwest of County Londonderry, Northern Ireland, at the entrance to Lough Foyle, within Causeway Coast and Glens district.

[2][3] The settlement of Magilligan Point on the lough is noted for its ferry crossing to Greencastle, County Donegal.

Colonel Thomas Colby chose Magilligan due to the flatness of the strand and its proximity to Scotland which, along with the rest of Britain, had been accurately mapped in previous decades.

[3] It is close to Bellarena railway station and there is a ferry service which operates during the summer season, connecting Magilligan with Greencastle across the lough.

Opening in July 1885 and closing in October 1885, it is the shortest lived passenger railway line in Ireland.
