The Jinghong Dam ({{zh|s=景洪大坝}}) is a gravity dam composed of roller-compacted concrete on the Lancang (Mekong) River near Jinghong in Yunnan Province, China. The main purpose of the dam is hydroelectric power production and it has an associated 1,750 MW power station.{{cite web|title=New hydropower station completed in Yunnan|url=http://www.chinadaily.com.cn/china/2008-06/19/content_6779088.htm|publisher=China Daily|accessdate=8 January 2011}} Part of the power generated is sold to Thailand under an agreement with China.{{cite web|title=Transmission Interconnection between Jinghong Hydropower Project in Yunnan Province to Thailand |url=http://www.adb.org/gms/pp_e3.asp |publisher=Asian Development Bank |accessdate=8 January 2011 |url-status=dead |archiveurl=https://web.archive.org/web/20050415143322/http://www.adb.org/GMS/pp_e3.asp |archivedate=15 April 2005 }}

{{as of|January 2020}} it is the nearest Chinese dam upstream of the Thai border, and has helped to cause huge fluctuations in river levels, affecting people's livelihoods downstream by disrupting the river's natural cycle. It, along with the many other dams on the river, is exacerbating the effects of climate change and impacting the ecosystem, disturbing the migratory patterns of fish as well as riverbank plants and local agriculture downstream.{{cite web |last1= Bainbridge |first1 =Amy|last2=Vimonsuk | first2=Supattra | title=Chinese dams are 'exacerbating' Mekong River drought, and locals say they've never seen it this low |publisher=Australian Broadcasting Corporation |website=ABC News | url=https://www.abc.net.au/news/2020-01-20/china-mekong-river-plan-creates-renewable-energy-but-costs-jobs/11872640 | access-date=20 January 2020|date=20 January 2020}}
