Nam Tok Sai Yok Noi (Thai: น้ำตกไทรโยคน้อย, lit. small Sai Yok waterfall) is a small town (thesaban tambon) in Sai Yok district, Kanchanaburi Province, Thailand, on the route of the so-called Death Railway linking Thailand with Burma as it was then called. After the war most of the railway was dismantled, leaving Nam Tok at the terminus. In 2003 the 1.4 km from Nam Tok station to Nam Tok Sai Yok Noi was reopened for easier access to the nearby Sai Yok Noi waterfall. However, as Sai Yok Noi is a single-platform terminus with no run-round loop, the line is only used by diesel multiple units.
