尿壶或尿盆是一种便器，功能与马桶类似，但只用来承接尿溺。旧时的尿壶经常在晚间置于卧室内，以便人们不出温暖的卧室就可小便，因此也称夜壶。

东亚有一种传统尿壶是开一小口承接小便，常制成老虎造型，因此又称虎子 (器物)。欧洲直到19世纪使用的尿盆一般为陶瓷制的有盖碗形，平时置于卧室床下。

冲水厕所出现以后，尿壶在日常生活中被逐渐淘汰，但医院中一些需长期卧床的病人仍会使用尿壶。

A chamber pot (also a jordan, a jerry, a guzunder, a po (possibly from French:pot de chambre), a potty pot, a potty, or a thunder pot) is a bowl-shaped container with a handle, and often a lid, kept in the bedroom under a bed or in the cabinet of a nightstand and generally used as a toilet at night. In Victorian times, some chamber pots would be built into a cabinet with a closeable cover.
