Si Narong (Thai: ศรีณรงค์, in Thai pronounced as /sǐː nā.rōŋ/) is a district (amphoe) of Surin province, northeastern Thailand.
The minor district (king amphoe) was established on 1 April 1995 with five tambons split from Sangkha 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): Sangkha, Lamduan and Sikhoraphum of Surin Province, Prang Ku and Khukhan of Sisaket province.
The district is divided into five sub-districts (tambons), which are further subdivided into 62 villages (mubans). There are no municipal (thesaban) areas. There are five tambon administrative organizations (TAO).
