Puffin Island (Welsh: Ynys Seiriol) is an uninhabited island off the eastern tip of Anglesey, Wales. It was formerly known as Priestholm in English (and Ynys Lannog/Glannog in Welsh). A hermitage was established here around the 6th century, and there are remains of a 12th-century monastery on the island. The island is also a Special Protection Area for wildlife.
