Amay Yay Yin (Burmese: အမေရေယဉ်; lit. 'mother of the stream or soft water underground', also known as Yayin Kadaw) is a prominent Burmese nat. She is recognized as one of the five mother nats, also referred to as "Anauk Medaw" ('royal mother of the west'). Unlike other Burmese nats, who became spirits after a violent death, Amay Yay Yin became a goddess without experiencing death.
