《马克白》（Macbeth）是莎士比亚最短的悲剧，也是他最受欢迎的作品之一。常被认为是他悲剧中最为阴暗、最富震撼力的作品。故事的地点设在苏格兰，并以戏剧的方式、通过心理作用、政治争斗的方式观察了追逐权势而背信弃义的邪恶。它大致根据苏格兰哲学家赫克托·波伊斯的《苏格兰国王麦克白》而写成。

戏剧讲述了勇敢的苏格兰将军马克白从三女巫得到预言，称他某日会成为苏格兰国王。出于野心和妻子的怂恿，马克白暗杀了国王邓肯，自立为王。在自责与幻想的折磨下，他很快堕落成为一名暴君，不得不通过持续的狠手来保护自己，打压敌意与猜忌。大屠杀与内战使得马克白与他的夫人变得自大、疯狂，直至二人最后的灭亡。舞台上，因马克白夫人的情绪起伏多变，很多人都认为那是最难演的女性角色之一。

Macbeth /məkˈbɛθ/ (full title The Tragedy of Macbeth) is a tragedy written by William Shakespeare. Set mainly in Scotland, the play dramatises the damaging physical and psychological effects of political ambition on those who seek power for its own sake. The play is believed to have been written between 1599 and 1606. The earliest account of a performance of what was probably Shakespeare's play is April 1611, when Simon Forman recorded seeing such a play at the Globe Theatre. It was first published in the Folio of 1623, possibly from a prompt book. It was most likely written during the reign of James I (of England), who had already been crowned James VI of Scotland before he succeeded to the English throne as well in 1603. James VI/I was a patron of Shakespeare's acting company, and of all the plays Shakespeare wrote during James's reign, Macbeth most clearly reflects the playwright's relationship with the sovereign.
