Acrisius (; ) was a
mythical king of
Argos, and a son of
Abas and
Aglaea (or
Ocalea, depending on the author), grandson of
Lynceus, great-grandson of
Danaus. His twin brother was
Proetus, with whom he is said to have quarreled even in the womb of his mother. When Abas died and Acrisius had grown up, he expelled Proetus from his inheritance; but, supported by his father-in-law
Iobates, the
Lycian, Proetus returned, and Acrisius was compelled to share his kingdom with his brother by giving
Tiryns to him, while he retained Argos for himself.
