Pong Nam Ron (Thai: โป่งน้ำร้อน, pronounced [pòːŋ ná(ː)m rɔ́ːn]) is the easternmost district (amphoe) of Chanthaburi province, eastern Thailand.

Neighboring districts are (from the southwest clockwise) Khlung, Makham, Khao Khitchakut, and Soi Dao of Chanthaburi province. To the east are Pailin and Battambang of Cambodia.

There are two border crossings into Cambodia in Pong Nam Ron:

• Ban Phakkat (Thai: บ้านผักกาด) in Klong Yai sub-district. On the Cambodian side of the border is Phsar Prum in Sala Krau district, Pailin province.
• Ban Laem (Thai: บ้านแหลม) in Thep Nimit sub-district. On the Cambodian side of the border is Daun Lem in Kamrieng district, Battambang province.

The minor district (king amphoe) Pong Nam Ron was upgraded to a full district on 25 July 1941.^[1]

The district is divided into five sub-districts (tambons), which are further subdivided into 47 villages (mubans). Pong Nam Ron is a township (thesaban tambon) which covers parts of tambons Pong Nam Ron and Thap Sai. There are a further five tambon administrative organizations (TAO).

Missing numbers are tambon which now form Soi Dao District.
