Wat Phra Yai, known in English as the Big Buddha Temple, is a Buddhist temple on Ko Phan (also spelled Koh Fan or Koh Faan), a small island offshore from the northeastern area of Ko Samui, Thailand, connected to that island by a short causeway 3 kilometres (1.9 miles) north of Samui International Airport.

Since being built in 1972, it has become one of Ko Samui's main tourist attractions and a major landmark.

[1] There is a second, smaller Buddha statue, depicting the Maitreya of the Future[1] and a collection of bells around the temple's rear side.

The temple design has elements of animism, Brahminism and Buddhism in its architecture.
