The Lam Phra Phloeng Dam (Thai: เขื่อนลำพระเพลิง, RTGS: Khuean Lam Phra Phloeng, pronounced [kʰɯ̀a̯n lām pʰráʔ pʰlɤ̄ːŋ]), is a dam on the Lam Phra Phloeng River, part of the Mun River catchment, in the Pak Thong Chai District, Nakhon Ratchasima Province, Thailand.

[1] Construction of the dam was completed in 1963, and its reservoir has suffered from very high levels of sedimentation resulting from erosion within its catchment area.

Its function is mainly irrigation water supply, although it generates electricity as well.

The sedimentation rates decreased gradually from the upstream to the crest of the dam.

The high sedimentation rate may be due to the inflow from the tributary as well as eroded materials that come from the upland area to the dam.
