恩斯特·托勒尔（Ernst Toller，1893年12月3日－1939年5月22日）是1920年代最出名的德国剧作家之一，也是德国表现主义戏剧的重要代表作者，与乔治·凯泽（Georg Kaiser）齐名。托勒尔的戏剧特色，在于他的戏剧与他的政治参与密切相关，几乎他的每一部剧作都带有政治主题，宣扬他的左倾政治理念。

托勒尔的重要剧作包括《转变》（Die Wandlung）、《群众与人》（Masse Mensch）、《德国青年亨克曼》（Der deutsche Hinkemann）、《哈啊！人生如斯》（Hoppla, wir leben!），诗集《燕子集》，以及自传《德国青年》（Eine Jugend in Deutschland，英译《我是德国人》I was a German）等。

Ernst Toller (1 December 1893 – 22 May 1939) was a German left-wing playwright, best known for his Expressionist plays. He served in 1919 for six days as President of the short-lived Bavarian Soviet Republic, and was imprisoned for five years for his actions. He wrote several plays and poetry during that period, which gained him international renown. They were performed in London and New York as well as Berlin. In 2000, several of his plays were published in an English translation.
