Sai Buri (Thai: สายบุรี, pronounced [sǎːj bū.rīː]) is a district (amphoe) in Pattani province, southern Thailand.

The local Malay people call it Teluban (Jawi: تلوبن), which is also the name of the only municipal area of the district, or Selindung Bayu (Jawi: سليندوڠ بايو), the Malay and Sanskrit word for 'wind shelter'.

Neighboring districts are (from the southeast clockwise): Mai Kaen of Pattani Province; Bacho of Narathiwat province; Kapho, Thung Yang Daeng, and Panare of Pattani.

In the thesaphiban administrative reforms at the beginning of the 20th century it became a province within the Monthon Pattani.

The highlight of Cino Kampong is the historic buildings, most of which are two-story half-timbered half-concrete shophouses built in the Sino-Malay architecture style, called "Cino Kampong", the only ones in the country and one-third of the world.
