班克斯（英语：Banksy，1970年代－），又译为班克西，是一位匿名的英国涂鸦艺术家、社会运动活跃份子、电影导演及画家。他的街头作品经常带有讽刺意味，在旁则附有一些颠覆性、玩世不恭的黑色幽默和精警句子；其涂鸦大多运用独特的模板技术拓印而成。他的作品富有浓厚政治风格，俨如一种以艺术方式表达的社会评论，并已经在世界各地不同城市的街道、墙壁与桥梁出现，甚至成为当地引人入胜的城市面貌。

班克斯的创作生涯源于早年参与布里斯托地下圈子，当中包括了不少艺术家与音乐人的跨界别合作。根据作家和图像设计师卓斯坦·文高（Tristan Manco）所说，Banksy是出生于1974年并在英国西南部布里斯托市成长的；另外文高又透露他是一名复印机技术员之子，最初是要学习当个肉店屠夫的，后来却备受1980年代后期在该城兴起的涂鸦热潮影响而深陷其中。有文化评论员指出，班克斯的绘图风格跟查维亚·普鲁（外号「Blek le Rat」）相近，后者从1981年便已经在巴黎开始从事模板印刷的艺术工作，组过庞克乐队，时至今日仍然活跃於伦敦的涂鸦艺术界。

Banksy is an England-based graffiti artist, political activist and film director of unverified identity. His satirical street art and subversive epigrams combine dark humour with graffiti executed in a distinctive stenciling technique. His works of political and social commentary have been featured on streets, walls, and bridges of cities throughout the world. Banksy's work grew out of the Bristol underground scene, which involved collaborations between artists and musicians. Observers have noted that his style is similar to Blek le Rat, who began to work with stencils in 1981 in Paris. Banksy says that he was inspired by "3D", a graffiti artist who later became a founding member of Massive Attack, an English musical group.
