Samut Songkhram (, ) is one of the central provinces (changwat) of Thailand.
Neighbouring provinces are (from the south clockwise) Phetchaburi, Ratchaburi and Samut Sakhon. Local people call Samut Songkhram Mae Klong. The province is the smallest in area of all Thai provinces. Chang and Eng Bunker, the famous Siamese twins were born here on 11 May 1811.
The word "samut" originates from the Sanskrit word à ¤¸à ¤®à ¥Âà ¤¦à ¥Âà ¤° samudra meaning 'ocean', and the word "songkhram" from Sanskrit à ¤¸à ¤Âà ¤Âà ¥Âà ¤°à ¤¾à ¤® saá¹ÂgrÃÂma meaning 'war'. Hence the name of the province literally means 'war ocean'. However, this province is colloquially known as "Mae Klong" after the name of the main river that flows past the area.
Samut Songkhram is at the mouth of the Mae Klong River to the Bay of Bangkok (upper Gulf of Thailand). With several canals (khlong) the water of the river is spread through the province for irrigation. At the coast are many lakes for producing sea salt.
