Llandwrog ( Welsh language: meaning 'The church of Saint Twrog') is a village and community in Gwynedd, north-west Wales, most notable for the presence of the headquarters of Welsh record label Sain and the site of Caernarfon Airport. It has a population of 2,466, increasing to 2,539 at the 2011 Census.
As suggested by the village name, the parish church is dedicated St Twrog.
It was the base of the first ever Sea and Mountain Rescue team, and includes the estate of Glynllifon.
RAF Llandwrog was a training airfield during World War II, and was later used as a weapons storage facility. It had a key role in Operation Sandcastle, where a large quantity of Nazi Tabun weapons were stored prior to eventual disposal at sea.
There is a local legend told about a midwife from Llandwrog. It is said that the she was once summoned by a stranger to an underground palace where she helped a queen give birth to a child. The stranger then gave the midwife some ointment for the baby's eyes. When the midwife accidentally touched it to her own eyes, the queen instantly changed into the midwife's former serving-maid, Eilian. Weeks later, when the midwife recognised the mysterious stranger at the local fair, she enquired about Eilian. The stranger replied that Eilian was well, and then asked the midwife which eye she saw him with. When she indicated the eye, he immediately poked it out.
