伊丽莎白塔（the
Elizabeth
Tower），旧称钟塔（the
Clock
Tower），俗称大本钟（Big
Ben），联合王国国会大厦威斯敏斯特宫的附属钟塔，世界上著名的哥特式建筑之一，伦敦乃至英国的标志性建筑。
伊丽莎白塔是坐落在英国伦敦泰晤士河畔的一座钟楼，是伦敦的标志性建筑之一。钟楼高95米，钟直径7米，重13.7吨。每15分钟响一次，敲响威斯敏斯特钟声。自从兴建地铁Jubilee线之后，伊丽莎白塔受到影响，测量显示伊丽莎白塔朝西北方向倾斜约半米。
伊丽莎白塔于1858年4月10日建成，是英国最大的钟。塔有320英尺高（约合97.5米），分针有14英尺长（约合4.27米），伊丽莎白塔用人工发条，国会开会期间，钟面会发出光芒，每隔一小时报时一次。每年的夏季与冬季时间转换时会把钟停止，进行零件的修补、交换、钟的调音等。
