In Greek mythology, Menoeceus (/məˈniːsiəs, -sjuːs/; Ancient Greek: Μενοικεύς, romanized: Menoikeús) was the name of two Theban characters. They are related by genealogy, the first being the grandfather of the second.
A later Menoeceus was a contemporary of Epicurus, to whom the philosopher wrote a letter summarizing his ethical doctrines.
