Aranyaprathet (Thai: อรัญประเทศ) is a town (thesaban mueang) in Sa Kaeo province in eastern Thailand.

Cambodian people cross the border daily with pushcarts and scooters with side cars loaded with their products.

The monsoon season is from late April to October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm.

Aranyaprathet lies on the Route 33, part of the route connecting Bangkok and Siem Reap, the city nearest Angkor Wat, and as a result sees a large volume of tourist traffic.

The road leads east to the border with Cambodia, and west to Sa Kaeo and Nakhon Nayok.
