两班（朝鲜语：양반／량반），朝鲜半岛的贵族阶级。韩国中央研究院引用20世纪统治者日本驻朝鲜统监府（总督府）统计数据，截止到20世纪30年代，一共有1,685个家庭是两班贵族家庭，大部分为在地两班，即使没有做官依然控制所在地区的人口和土地，干涉地方行政。很多贵族家庭有500年或者500年以上贵族历史，大约50%以上的贵族家庭有300年到400年以上贵族历史，只有不到2%的贵族家庭成为贵族不超过一百年。日韩合并之后，很多贵族因为反抗日本统治，遭受统监府没收财产，部分贵族家庭进入中国，部分家庭进入日本。直到二次大战之后，大韩民国归还两班财产，但只限于韩国从日本统治者接收下的土地和财产。 两班是古代朝鲜贵族阶级，雏形出现在朝鲜三国时代，主要形成于高丽国、李氏朝鲜时期。是古代高丽国和李氏朝鲜的贵族统治阶级与学者官吏。

The yangban (Hangul: 양반: Hanja: 兩班) were part of the traditional ruling class or gentry of dynastic Korea during the Joseon Dynasty. The yangban were mainly composed of civil servants and military officers. The yangban were landed or unlanded aristocracy who comprised the Korean Confucian idea of a "scholarly official." Basically, they were administrators and bureaucrats who oversaw ancient Korea's traditional agrarian bureaucracy until the medieval regime of Joseon Dynasty ended in 1894. In a broader sense, office holder's family and descendants as well as country families who claimed such descendance were socially accepted as yangban.
