塞拉门尼斯（古希腊语：Θηραμένης，Thēraménēs, 前411年－前404年在位），是一名雅典政治人物，在伯罗奔尼撒战争的最后十年中声名显赫。他曾参与了雅典的两代寡头政府，并在前406年参与了对阿吉纽西战役指挥将军的审判。作为寡头执政者中的温和派，他游走与民主派与极端寡头派之间。前411年，他成功地组建了一个更广泛的寡头政府；然而在前404年，他却未能再次达到这一目标，反而遭其反对的极端寡头派处决。

Theramenes (/θᵻˈræmᵻniːz/; Greek: Θηραμένης; died 404 BC) was an Athenian statesman, prominent in the final decade of the Peloponnesian War. He was particularly active during the two periods of oligarchic government at Athens, as well as in the trial of the generals who had commanded at Arginusae in 406 BC. A moderate oligarch, he often found himself caught between the democrats on the one hand and the extremist oligarchs on the other. Successful in replacing a narrow oligarchy with a broader one in 411 BC, he failed to achieve the same end in 404 BC, and was executed by the extremists whose policies he had opposed.
