Na religião e mitologia gregas antigas, Iaco (também Iacos) (, Iakchos) era uma divindade menor, de alguma importância cúltica, particularmente em Atenas e Elêusis em conexão com os mistérios eleusianos, mas sem nenhuma mitologia significativa.Graf 2005, "Iacchus"; Hard, p. 134; Grimal, s.v. Iacchus, p. 224; Tripp, s.v. Iacchus; Rose, Oxford Classical Dictionary s.v. Iacchus; Smith, s.v. Iacchus. Ele talvez tenha se originado como a personificação da exclamação ritual Iacche!, gritada durante a procissão eleusiana de Atenas a Elêusis.Compare com Himeneu, cujo nome derivou de um grito de casamento tradicional, ver Hard, p. 223. Ele era frequentemente identificado com Dioniso, talvez por causa da semelhança dos nomes Iaco e Baco, outro nome para Dionísio. Por vários relatos, ele era filho de Deméter (ou aparentemente seu marido), ou um filho de Perséfone, idêntico a Dioniso Zagreu, ou um filho de Dioniso.
Durante as guerras greco-persas, quando o interior ático, desertado pelos gregos, estava sendo devastado pelos persas, uma procissão fantasmagórica foi supostamente vista avançando a partir de Elêusis, gritando "Iaco". Este evento milagroso foi interpretado como um sinal da eventual vitória grega na Batalha de Salamina (480 a.C.).Herodotus, 8.65. Iaco também estava possivelmente envolvido em um mito eleusiano em que a velha Baubo, expondo seus órgãos genitais, animava Deméter, que estava de luto.
Culto Iaco era uma das divindades, junto com Deméter e Kore (Perséfone), adoradas como parte dos Mistérios de Elêusis.Jiménez San Cristóbal 2012, p. 125. O geógrafo do final do século I a.C. Estrabão chamou-o de ἀρχηγέτην ("líder-em-chefe" ou "fundador") "dos mistérios".Estrabão, 10.3.10; Farnell, p. 146. No entanto Farnell, p. 148, argumentando que Iaco foi uma adição tardia aos mistérios eleusianos, desconta Iaco como "fundador dos mistérios", dizendo: "se Estrabão, em denominando [Iaco] o ἀρχηγέτης τῶν μυστηρίων, significa mais além de que ele levava os mystae pelo caminho sagrado para o santuário místico, não precisamos ser influenciados por Estrabão contra melhores evidências".
