《理查三世》是英国剧作家威廉·莎士比亚的作品，描述了理查三世短暂的执政时期，该剧本被认为创作于大约1591年。这部戏剧有时被分类为悲剧（早期的四开本），但是更准确的分类应为历史剧，如《第一对开本》中作品分类。作品从《亨利六世第三部》展开故事情节，成为从《理查二世》开始的系列历史剧的结束。该作品是莎士比亚第二长的剧本，仅次于《哈姆雷特》，由于《第一对开本》中收录的《哈姆雷特》版本短于先前的四开本，因此《理查三世》是其中最长的剧本。剧本的长度通常被认为是一个缺点，因为太长而很少被完整地表演，一些不重要的人物常常被删减。(Richard III is a work of British dramatist William Shakespeare. It has described the short ruling period of Richard III and was thought to be written in 1591 or so. Sometimes this drama was classified as a tragedy (the former quarto), but it should be a historical play in according with the work classification in First Folio. The work was developed from Henry VI, part 3 and has became the ending of series historical plays with the beginning of Richard II. It is the second longest play of Shakespeare only next to Hamlet. Because the Hamlet recorded in First Folio is shorter than the former quarto, Richard III has been the longest one.but the length of the play often be considered as a shortcoming, it is too long to be fully performed and usually some unimportant figures are deleted.)
