Si Songkhram (Thai: ศรีสงคราม, in Thai pronounced as /sǐː sōŋ.kʰrāːm/) is a district (amphoe) in Nakhon Phanom province in northeast Thailand.
Neighboring districts are (from the north clockwise): Na Thom, Ban Phaeng, Tha Uthen, Phon Sawan, and Na Wa of Nakhon Phanom Province, and Akat Amnuai of Sakon Nakhon province.
The district is named after its main river, the Songkhram River.

On 1 April 1926, it was split off as the minor district (king amphoe) Akat Amnui (อากาศอำนวย), the present day Akat Amnui District in neighboring Sakon Nakhon was also originally controlled from Tha Uthen. The minor district consisted of the seven tambons: Na Wa, Ban Kha, Ban Siao, Sam Phong, Ban Waeng, Na Thom, and Ban Phaeng.[1] The minor district was renamed Si Songkhram in 1939,[2] and was upgraded to a full district on 10 March 1953.[3]
