Neighboring provinces are (from the southwest clockwise) Samut Songkhram, Ratchaburi, Nakhon Pathom, and Bangkok. Samut Sakhon is part of the Bangkok Metropolitan Region.


The word samut originates from the Sanskrit word samudra meaning 'ocean', and the word sakhon from Sanskrit sagara meaning 'lake'.


Samut Sakhon is at the mouth of the Tha Chin Klong River, a distributary of the Chao Phraya River, to the Gulf of Thailand. At the coast are many salt pans used for harvesting sea salt.


The oldest name of the area is Tha Chin ('Chinese pier'), probably referring to the fact that it was a trading port where Chinese junks arrived.[1] In 1548 the city Sakhon Buri was established, and was renamed Mahachai in 1704 after the khlong Mahachai which was dug then and connected with the Tha Chin River near the town. King Mongkut gave it its current name, but the old name Mahachai is still sometimes used by the locals.


The most polluted air in Thailand in 2018 was in Samut Sakhon Province.[2]


The provincial seal shows a Chinese junk in front of the coast, with a smoking chimney. Both refer to the old trading tradition as well as the local industries.

The provincial tree is the devil tree (Alstonia scholaris). The provincial slogan is "Fishing city, factory town, agricultural ground, historic site".


Samut Sakhon is a leading sea salt producer. According to a survey in 2011, 12,572 rai of salt pans were managed by 242 families in Samut Sakhon.[3]

Administrative divisionsEdit

The province is divided into three districts (amphoes). The districts are further subdivided into 40 communes (tambons) and 288 villages (mubans).

  1. Mueang Samut Sakhon
  2. Krathum Baen
  3. Ban Phaeo

Altogether there are seven municipal (thesaban) areas within the province. Samut Sakhon is the only city (thesaban nakhon)[citation needed]. Krathum Baen and Om Noi are the two towns (thesaban mueangs)[citation needed], and there are a further four townships (thesaban tambons). The non-municipal areas are administered by 30 tambon administrative organizations (TAO).
