Nakhon Pathom (Thai: จังหวัดนครปฐม, pronounced [náʔkʰɔ̄ːn pā.tʰǒm], (Pronunciation)) is one of the central provinces (changwat) of Thailand. Neighbouring provinces are (from north clockwise) Suphan Buri, Ayutthaya, Nonthaburi, Bangkok, Samut Sakhon, Ratchaburi, and Kanchanaburi. The capital city of Nakhon Pathom province is Nakhon Pathom.
Nakhon Pathom province is home to the Phra Pathommachedi, a chedi commissioned by King Mongkut (Rama IV) and completed by King Chulalongkorn (Rama V) in 1870. The chedi is a reminder of the long vanished Dvaravati civilization that once flourished here and by tradition Nakhon Pathom is where Buddhism first came to Thailand. The province itself is known for its many fruit orchards.
