Wat Saphan Rueak 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 Khanun and Wat Khanan. Wat Saphan Rueak was situated between Wat Dusit and Wat Khanun.
The monastery's historical background and period of construction are unknown.
The former location of Wat Saphan Rueak 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.
