Loeng Nok Tha (Thai: เลิงนกทา, pronounced [lɤ̄ːŋ nók tʰāː]; Northeastern Thai: เลิงนกทา, pronounced [lɤ᷇ːŋ nòk tʰa᷇ː]) is a district of Yasothon province in northeastern Thailand.

It then consisted of the three tambons Kut Chiang Mi, Bung Kha, and Som Pho.

[1] On 1 November 1947, Loeng Nok Tha was elevated to district (amphoe) status in Ubon Ratchathani Province.

The name Loeng Nok Tha consists of two parts: The area of Loeng Nok Tha is so called because there once were large numbers of nok tha living around the swamps of the region, but they have now disappeared almost entirely as a result of human habitation; not to be confused with similarly named Tambon Nong ('fen') Nok Tha (Thai: หนองนกทา) in Khemarat district, Ubon Ratchatani Province; or None ('hill') Nok Tha (Thai:โนนนกทา) a Thai prehistoric archaeological site in Phu Wiang district, Khon Kaen Province.

The district is divided into 10 sub-districts (tambons), incorporating 143 villages (mubans).
