在希腊神话中，阿洛伊代（希腊语：Αλοαδαι，英语：Aloadae）为波塞冬和伊菲美迪亚生育的巨人双胞胎。那两人为奥图斯（Οτος）和厄菲阿尔忒斯（Επηιαλτες），他们曾想摧毁奥林匹斯山。而厄菲阿尔忒斯被阿波罗用箭射死。

In Greek mythology, the Aloadae (/ˌæloʊˈeɪdiː/) or Aloads (Ancient Greek: Ἀλωάδαι Aloadai) were Otus (or Otos) (Ὦτος) and Ephialtes (Ἐφιάλτης), sons of Iphimedia, wife of Aloeus, by Poseidon, whom she induced to make her pregnant by going to the seashore and disporting herself in the surf or scooping seawater into her bosom. From Aloeus they received their patronymic, the Aloadae. They were strong and aggressive giants, growing by nine fingers every month nine fathoms tall at age nine, and only outshone in beauty by Orion.
