Khan Na Yao (Thai: คันนายาว, in Thai pronounced as /kʰān nāː jāːw/) is one of the 50 districts (khet) of Bangkok, Thailand. It is bounded by other Bangkok districts (from north clockwise): Bang Khen, Khlong Sam Wa, Min Buri, Saphan Sung, and Bueng Kum.
Khan Na Yao was separated from Bueng Kum on 14 October 1997 announcement, effective 21 November 1997, together with Saphan Sung.[3]
Its name means "long paddy-field ridge", describing the geography of the district in the past; Khan Na Yao was an agricultural district. Until now, the rice fields and its ridges are long gone; they are part of the present-day Seri Thai road.
The district is divided into two sub-districts (khwaeng).
