Phra Non Saen Riyan, also known as Luang Pho Saen Riyan, is the name of a circa nineteen meter long and three meter tall, and more than 300 year old reclining Buddha at Wat Bang Noi, in Samut Songkhram Province.

The Buddha image is now covered with various old and new Thai coins, said to number several 100,000, and both of brass-like aluminium bronze, copper and nickel, making it  sparkle in gold, metallic brown and silver colours, due to pae riyan.
