Khuan Niang (Thai: ควนเนียง, pronounced [kʰūa̯n nīa̯ŋ]) is a district (amphoe) of Songkhla province, southern Thailand.

The minor district (king amphoe) was established on 2 January 1985 by splitting off four tambons from Rattaphum district.

The district is divided into four sub-districts (tambons), which are further subdivided into 46 villages (mubans).
