Wat Wachira Thammaram is a Buddhist temple in Ayutthaya affiliated with the Dhammayutika Nikaya, a sub-sect of the Theravada school of Buddhism.

In front of the ubosot, the ordination hall, stands a bronze statue of King Mongkhut, i.e. Rama IV (fig.), who in 1833 founded the Dhammayutika sect.

The temple is part of Phuttha Uthayaan Maharaat (fig.), a site that encompasses an area of over 200 rai.

The main altar inside the ordination hall features a golden Buddha statue, seated in the maravijaya pose.

Below it stands a smaller statue of a crowned Buddha, a bronze replica of the principal golden Buddha statue housed in the temple's wihaan.
