'''Iocaste''' ({{lang-gr|Ιοκάστη}}), juga dikenal sebagai '''{{nowrap|Jupiter XXIV}}''', adalah [[satelit alami|satelit]] [[retrograde]] [[satelit ireguler|ireguler]] [[Jupiter]]. Iocaste ditemukan oleh tim astronom dari [[Universitas Hawaii]] yang dipimpin oleh [[Scott S. Sheppard]] pada tahun 2000, dan diberi sebutan sementara '''{{nowrap|S/2000 J 3}}'''.<ref>{{cite web |author=Daniel W. E.

Iocaste mengorbit Jupiter pada jarak rata-rata sebesar 20,723 juta km dalam waktu 609,427 hari, dengan [[inklinasi]] sebesar 147° terhadap [[ekliptika]] (146° terhadap khatulistiwa Jupiter) dengan [[Eksentrisitas orbit|eksentrisitas]] sebesar 0,2874.
