Wat Khanun was a monastery situated off the city island in the eastern area of Ayutthaya in Phai Ling sub-district. The temple was located on the east bank of Khlong Dusit on the same north-south axis as Wat Dusit, Wat Saphan Rueak, and Wat Khanan. Wat Khanun was situated between Wat Saphan Ruek and Wat Khanan.
The monastery's historical background and period of construction are unknown.
The old texts recount that inhabitants from Ang Thong, Lopburi, Inburi, Phromburi, Singburi, Sanburi (1) and Suphanburi brought in paddy by boats and moored in front of Wat Samo, Wat Khanun and Wat Khanan, where they sold their merchandise. The local villagers in the vicinity of these three temples set up rice mills. The milled rice was sold in the city and to the local Chinese liquor distillers at Pak Khao San village. In the season when the junks set sail for China milled rice was sold as provisions for the junks. 
The former location of Wat Khanun is situated in a build-up area and there are likely no traces visible of the monastery anymore above ground level. The site has not been excavated as yet.
