Kepone, also known as chlordecone, is an organochlorine compound. It is a colourless solid. This compound is a controversial insecticide related to Mirex and DDT. Its use was so disastrous that it is now prohibited in the western world, but only after many millions of kilograms had been produced.〔Robert L. Metcalf "Insect Control" in ''Ullmann's Encyclopedia of Industrial Chemistry'' Wiley-VCH, Wienheim, 2002. 〕 Kepone is a known persistent organic pollutants (POP), classified among the "dirty dozen" and banned globally by the Stockholm Convention on Persistent Organic Pollutants as of 2011.

The LC50 (LC = lethal concentration) is 0.022–0.095 mg/kg for blue gill and trout. Kepone bioaccumulates in animals by factors up to a million-fold. Workers with repeated exposure suffer severe convulsions resulting from degradation of the synaptic junctions.〔
