The Chaine Memorial Tower in Larne, County Antrim, Northern Ireland, is a memorial to James Chaine, a former Member of Parliament for Antrim, who died in 1885. It is a cylindrical stone tower lighthouse with a conical roof, situated on the west side of entrance to Larne Lough.
Chaine developed Larne's short sea route to Scotland as well as establishing the town as a transatlantic port. The memorial, built in 1888, by public subscription, is a replica of an Irish round tower. The memorial is situated at the mouth of Larne harbour, and is reached via Chaine Memorial Road. There is access from Curran Road via Bay Road.
