The Coleraine–Portrush line is a short railway branch line in Northern Ireland between the town of Coleraine in County Londonderry and the seaside resort of Portrush in County Antrim. The line, which is operated by NI Railways, has two intermediate halts and connects to the main Belfast–Derry line at Coleraine.

On Saturdays the first train from Portrush is a through train to Belfast Grand Central; then the rest of the day an hourly service operates to Coleraine and Portrush.

The line was built as part of the Ballymena, Ballymoney, Coleraine and Portrush Junction Railway, authorised in 1853. The engineer was Charles Lanyon and the contractor and major sponsor of the line was William Dargan. It was opened in 1855. In 1860, a junction with the Derry line was made at Coleraine, leaving the line from there to the terminus at Portrush as a branch.^{[1][page needed]}

Winter services were suspended from 1960, but opening of the New University of Ulster near Coleraine saw them restored, together with the addition of new halts at University (1968) and Dhu Varren (1969), to cater for student travel.^{[citation needed]}

The intermediate station for Portstewart (via the Portstewart Tramway) was located at Cromore and closed in 1964. This station then reopened in 1968 but closed again in 1988.^{[2][page needed]}
