Llanaelhaearn is a village and community on the Llyn Peninsula.
The settlement is traditionally credited to its patron saint, a disciple of Saint Beuno, who was supposed to have been resurrected nearby. Both Aelhaiarn and Beuno were noble monks from Powys who came north under the patronage of King Cadfan of Gwynedd, settling in the area of Clynnog and Llanaelhaearn. The church at Llanaelhaearn (NPRN 43685) bears walls from around the twelfth century and during expansion of the churchyard in 1865, workers discovered the Latin-inscribed gravestone of an Aliortus of Elmet (57658), possibly indicating the existence of a religious settlement at the site before the arrival of Beuno's followers. St Aelhaiarn's Well (Ffynnon Aelhaearn) was a major station on the northern pilgrimage route to Bardsey Island and much frequented for the miraculous cures associated with the "laughing" or "troubling of the water", an irregular appearance of upwelling bubbles throughout its basin.

The village was photographed during aerila reconnaissance in June 2017.
