Sam Khok (Thai: สามโคก, pronounced [sǎːm kʰôːk]) is a district (amphoe) in the northern part of Pathum Thani province, central Thailand, about 50 kilometres north of Bangkok.

[citation needed] In 1726 a book entitled, Oud En Niew Oost-Indien was published in Holland by the Dutch cartographer, De Groote.

In it, De Groote's map called "Siamese Rievier Menam" describes Sam Khok as a Potte Bakkers Drop ('pottery-making village').

King Vajiravudh (Rama VI) later renamed the city Pathum Thani, but the meaning is unchanged.

[citation needed] Neighbouring districts are (from the north clockwise): Lat Bua Luang and Bang Sai of Ayutthaya province; Khlong Luang, Mueang Pathum Thani, and Lat Lum Kaeo of Pathum Thani Province.
