《奥赛罗》（Othello: The Moor of Venice）是莎士比亚大约于1603年所写作的一出悲剧。戏剧被认为是根据意大利短篇小说《一位摩尔上尉》(Un Capitano Moro)改编而成，后者是由乔凡尼·薄伽丘的门徒吉拉尔迪·钦齐奥写成，并于1565年出版。剧情围绕这四位角色展开：供职威尼斯部队的摩尔军奥赛罗；妻子苔丝狄蒙娜；副将凯西奥；和骗取他信任的旗官伊阿古。由于戏剧情节跌宕起伏，涉及种族、爱情、嫉妒、背叛，《奥赛罗》依然常在今天上演，并为众多作品提供了创意基础。

Othello (The Tragedy of Othello, the Moor of Venice) is a tragedy by William Shakespeare, believed to have been written in 1603. It is based on the story Un Capitano Moro ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. This tightly constructed work revolves around four central characters: Othello, a Moorish general in the Venetian army; his beloved wife, Desdemona; his loyal lieutenant, Cassio; and his trusted but ultimately unfaithful ensign, Iago. Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, Othello is still often performed in professional and community theatre alike, and has been the source for numerous operatic, film, and literary adaptations.
