Loreto College is a Roman Catholic grammar school situated in the Castlerock Road area of Coleraine, County Londonderry, on the north coast of Northern Ireland. Loreto College educates both girls and boys between the age of 11 and 18.

In 1906, the Ursuline Order took control of an all-girls school, setting up a smaller boys' primary school nearby. In 1922, when the new Northern Ireland Educational Authority was set up, certain qualifications were needed to teach in secondary schools. The nuns, being French, did not have these qualifications so they decided to withdraw from Northern Ireland. The Loreto nuns in Omagh were asked to take over the schools, both primary and secondary. On August 13, 1930, four Loreto Sisters, a congregation founded by Mary Ward, arrived. The Ursulines stayed with them for two weeks to help them settle into their new home. The original four sisters - M. Rose, M. Colmcille, M. Aidan and M. Kevin - were joined by M. Peter, M. Benedict and M. Gertrude as first members of the new community. The school was later extended, and has adapted to changes in the educational system . The school became co-educational in 1977. is owned and maintained by the Loreto Education Trust. In 2005, the school celebrated its 75th anniversary, culminating in an open day including a museum, and finally Mass in St. John's Church nearby. In April 2014, after 83 years of living in the convent house attached to the school, the Loreto Sisters left as the home did not meet fire regulations.
