Tris(ethylenediamine)cobalt(III) chloride is an inorganic compound with the formula [Co(en)₃]Cl₃ (where "en" is the abbreviation for ethylenediamine). It is the chloride salt of the coordination complex [Co(en)₃]³⁺. This trication was important in the history of coordination chemistry because of its stability and its stereochemistry. Many different salts have been described. The complex was first described by Alfred Werner who isolated this salt as yellow-gold needle-like crystals.
