Wat Trai Saranakhom is a Mahayana Buddhist temple in Bang Pakong District, Chachengsao Province, that was established in 1938 and was originally known as Wat Song Khlong.

The most notable sculpture at the temple is an outdoor statue depicting a giant monk on pilgrimage, known as Luang Poo Pahng Thudong Yai (fig.). Portrayed in the  ascetic wandering tradition, the figure symbolizes renunciation, perseverance, and spiritual discipline.

In its iconography, the statue is reminiscent of Phra Siwalih (fig.), a revered arahat in Theravada Buddhism, celebrated as a paragon of good fortune, abundance, and merit acquired through ascetic practice.
