Non Narai (th|โนนนารายณ์, pronounced as /th/) is a district (amphoe) of Surin province, northeastern Thailand.
The minor district (king amphoe) was established on 1 July 1997, when five tambons were split from Rattanaburi district.[1]
On 15 May 2007, all 81 minor districts were upgraded to full districts.[2] On 24 August the upgrade became official.[3]
Neighboring districts are (from the south clockwise): Samrong Thap, Sanom and Rattanaburi of Surin Province, and Mueang Chan of Sisaket province.
The district is divided into five sub-districts (tambons), which are further subdivided into 67 villages (mubans). There are no municipal (thesaban) areas, and further five tambon administrative organizations (TAO).
