Sai Mai (Thai: สายไหม, pronounced [sǎːj mǎj]) is one of the 50 districts (Khet) of Bangkok, Thailand. It is bounded by (from north clockwise): Amphoe Lam Luk Ka of Pathum Thani Province; Khlong Sam Wa, Bang Khen and Don Mueang of Bangkok. As of 2014, it had the highest population of all districts in Bangkok.


Sai Mai was the name of a muban in tambon Khu Khot, Amphoe Lam Luk Ka, Pathum Thani Province. It was transferred to Amphoe Bang Khen and promoted to a subdistrict (Tambon) in 1940. Due to the growth of population in the area, Sai Mai was elevated to a district effective 21 November 1997 to improve the service and administration.[2]
