'''Sai Mai''' ({{langx|th|สายไหม}}, {{IPA|th|sǎːj mǎj|pron}}) is one of the [[Districts of Bangkok|50 districts]] (''khet'') of [[Bangkok]], [[Thailand]]. It is bounded by (from north clockwise): [[Lam Luk Ka district]] of [[Pathum Thani province]]; [[Khlong Sam Wa]], [[Bang Khen]] and [[Don Mueang]] of Bangkok.
==History== Sai Mai was the name of a ''[[muban]]'' (village) in ''[[tambon]]'' (sub-district) [[Khu Khot]], Lam Luk Ka District, Pathum Thani Province. It was transferred to [[Bang Khen#History|Bang Khen district]] and promoted to subdistrict (''[[tambon]]'') in 1940. Due to the growth of population in the area, Sai Mai was elevated to district status effective 21 November 1997 to improve service and administration.<ref>{{cite journal|journal=Royal Gazette|volume=114|issue=พิเศษ 108 ง|pages=6|script-title=th:ประกาศกระทรวงมหาดไทย เรื่อง เปลี่ยนแปลงพื้นที่เขตบางเขน เขตลาดพร้าว เขตบึงกุ่ม เขตประเวศ และตั้งเขตสายไหม เขตคันนายาว เขตสะพานสูง|url=http://www.ratchakitcha.soc.go.th/DATA/PDF/2540/E/108/6.PDF|archive-url=https://web.archive.org/web/20111107231426/http://www.ratchakitcha.soc.go.th/DATA/PDF/2540/E/108/6.PDF|url-status=dead|archive-date=7 November 2011|date=1997-11-18|language=Thai}}</ref>
The name of the village, "Sai Mai" (which can be interpreted as "late or not?"), is believed to have come from a common question in the past. Because the area was once so far from downtown, people often asked, "Will we be late getting here ?" The name has no connection to the sweet snack ''[[roti sai mai]]''.<ref>{{cite web|url=https://mgronline.com/columnist/detail/9630000127739|work=ASTV Manager|date=2020-12-15|access-date=2021-02-05|language=thai|title="สายไหม" ในวันที่รถไฟฟ้าสายสีเขียวมาถึงคูคต|trans-title="Sai Mai" on the day when the Green Line Skytrain arrived in Khu Khot|first=Kittinan|last= Naktong}}</ref>
The dominant feature of the district is [[Khlong]] (canal) Lat Phrao. The canal is thought to have been dug in the early period of the [[Rattanakosin Kingdom (1782–1932)]]. Khlong Lat Phrao is one of nine canals in Bangkok that drains rainwater flowing into the city from northern Thailand, but it has been neglected for decades and clogged with refuse. In January 2016, 1.6 billion [[Thai baht|baht]] was allocated to rehabilitate the canal, widen it to 38 metres and deepen it to four metres. Construction is to be completed by June 2019.<ref name="BP-20190407">{{cite news |last1=Wancharoen |first1=Supoj |title=Canal's redevelopment sees local hopes swell |url=https://www.bangkokpost.com/news/special-reports/1657964/canals-redevelopment-sees-local-hopes-swell#cxrecs_s |access-date=2019-04-07 |work=Bangkok Post |date=2019-04-07}}</ref>
