Acontia is a genus of moths of the family Noctuidae. The genus was named by Ferdinand Ochsenheimer in 1816. Eusceptis, Pseudalypia and Spragueia are sometimes included in the present genus, but here they are tentatively treated as different pending further research. Many species of Tarache were also once placed here (see below).
