埃勾斯（古希腊语：Αἰγεύς）希腊神话中的雅典国王，阿提卡英雄忒修斯的父亲。

根据神话，埃勾斯是雅典国王潘狄翁的儿子，刻克洛普斯的孙子。潘狄翁被同族人墨提翁的几个儿子（欧帕拉摩斯、西库翁和代达罗斯）赶下王位，被迫逃亡到墨伽拉，娶了当地国王皮拉斯的女儿皮利亚。皮利亚为潘狄翁生四子：埃勾斯、帕拉斯、尼索斯和吕科斯。潘狄翁死后，埃勾斯和他的三个兄弟进军雅典，从墨提翁的儿子们手中夺回了政权。之后兄弟四人分享了权力，但以埃勾斯为国王。另有一说为，篡夺雅典政权的是半人半兽的怪物珀透斯，埃勾斯是从珀透斯手中夺回的雅典。

In Greek mythology, Aegeus (/ˈɛdʒˌjuːs/; Ancient Greek: Αἰγεύς) or Aegeas (/ˈiːdʒiəs/; Αιγέας), was an archaic figure in the founding myth of Athens. The "goat-man" who gave his name to the Aegean Sea was, next to Poseidon, the father of Theseus, the founder of Athenian institutions and one of the kings of Athens.
