Phan Thong (Thai: พานทอง, pronounced [pʰāːn tʰɔ̄ːŋ]) is a district (amphoe) of the province of Chonburi in Thailand.

The church was founded by Francois Marie Guego, a French missionary who arrived in Thailand in 1867.

The community, the largest landholder in the area, is under pressure from developers to sell the property to feed the industrialization fostered by the Eastern Economic Corridor.

It is said that its name is distorted from the name of a local hunter (phran in Thai) "Thong", who led warlord Phraya Tak to flee the Burmese army from Ayutthaya to the eastern region during the second fall of Ayutthaya, before the counterattack and established himself as a new king Taksin the Great.

[2] Phan Thong is divided into 11 sub-districts (tambons), which are further subdivided into 76 administrative villages (mubans).
