Llanilar (Welsh pronunciation: [ɬanˈɪlar]) is a village and community in Ceredigion, Wales, about 4 kilometres (2.5 mi) southeast of Aberystwyth.

This town's name honours its patron saint, although it is disputed whether that is the church's presumed founder Ilar (Welsh for "Hilary"),[2] listed as a member of Cadfan's mission and a martyr but now almost totally forgotten, or the more famous Hilary who was bishop of Poitiers in France and is still celebrated by the Anglican and Catholic churches in Wales.

The present village was built along the southern side of the scenic River Ystwyth and contains a parish church, Nonconformist chapel, primary school, GP Surgery, and garage.

St Hilary's Church[4] (Eglwys Sant Ilar) has a large square tower, chancel, nave, and porch.

In the porch is a hollowed stone for holding holy water and, above the door, there is an ancient beam with carved heads and animals inscribed with the words J.S.
