Maghera Old Church (also known as Old St. Lurach's Church) is the ruins of a church in Maghera, County Londonderry, Northern Ireland. It is a scheduled monument and a Monument in State Care. It was originally founded by St Lurach at some point during the 6th century, likely as a monastery. It is mentioned in the Annals of Ulster when it was plundered by Vikings in 835 and many of its abbots killed. The church later suffered significant damaged when it was burned in 1135.
