Si Maha Phot (th|ศรีมหาโพธิ, pronounced as /th/) is a district (amphoe) in the southern part of Prachinburi province, eastern Thailand. The name may also be spelled Sri Maha Bodhi, and honours the Bodhi tree (ต้นพระศรีมหาโพธิ์.)

The plant, opened in March 2016, has an initial production capacity of 60,000 vehicles per year. The plant is designed to build up to 120,000 vehicles per year.[2]
The air quality in the district in 2018 was the eighth worst in Thailand.[3]

There are two townships (thesaban tambons): Si Maha Phot covers parts of tambons Si Maha Phot and Nong Phrong, and Krok Sombun covers parts of Krok Sombun.
