Wat Apson Sawan Worawihan (Thai: วัดอัปสรสวรรค์วรวิหาร), also simply known as Wat Apson Sawan is an ancient Thai Buddhist temple more than 200 years in Bangkok.

Later on, during the reign of King Nangklao (Rama III), Royal Concubine Noi (Suranakong) has restored the temple.

What is interesting about this temple include ubosot (ordination hall) and vihāra (sanctuary) were built in Chinese style like neighbouring Wat Nang Chi.

Enshrined inside ubosot are 28 in similar shape and size principal Buddha images in Māravijaya posture created by order of King Nangklao, as well as ho trai (Tripiṭaka hall) a whole wooden library built with Ayutthaya period art in the middle of a pond.

Wat Apson Sawan was declared a national historic site by the Fine Arts Department in 1977.
