Llandecwyn is a hamlet and former parish stretching from the estuary of the Afon Dwyryd to the hills of the Rhinogs in Gwynedd, Wales. The lower part of the hamlet around Cilfor is served by Llandecwyn railway station. Today the former parish is part of the Bro Ardudwy ministry area, which includes Harlech, a few kilometres to the southwest, and Barmouth. The church of Saint Tecwyn lies at an altitude of a little over 150m, and is the only ancient church in Meirionnydd not on the coast (although the present building is actually Victorian). It is dedicated to Saint Tecwyn and boasts spectacular views over northern parts of Cardigan Bay and across to Portmerion.
The church marks the end of the pilgrimage route, Saint Tecwyn's Way. This starts at the church of Llanfihangel-y-traethau to the southwest, which has a window depicting the saint coming ashore in his coracle.
16th century bible translator and hymn writer Edmund Prys was born in the parish.
