Thung Khao Luang (Thai: ทุ่งเขาหลวง, pronounced [tʰûŋ kʰǎw lǔaŋ]; Northeastern Thai: ท่งเขาหลวง, pronounced [tʰōŋ kʰǎw lǔaŋ]) is a district (amphoe) of Roi Et province, Thailand.

Neighboring districts are (from the south clockwise): At Samat, Thawat Buri, and Selaphum.

The minor district was created on 1 July 1997, when the four tambons Thung Khao Luang, Thoet Thai, Bueng Ngam, and Maba were split off from Thawat Buri district.

[3] The district is divided into five sub-districts (tambons), which are further subdivided into 50 villages (mubans).

[4] Local officials claim the number of resident Swiss is overstated as most live with their wives in Switzerland.
