雨漏，又称滴水嘴兽，是建筑输水管道喷口终端的一种雕饰。它一般是雕刻成动物或鬼怪模样，作用在于把屋顶上流下来的雨水通过嘴上的空排出，以免雨水沿着建筑物的墙壁流下来。这样可以防止雨水侵蚀墙壁石块之间的砂浆。建筑师在设计建筑物的时候往往使用多个雨漏让雨水有多个排出的地方，以免在下大雨时水来不及排出。一般来说滴水嘴兽的形状是伸长了的神奇动物的样子，雨漏的身体越长，水排出时离墙壁的距离就越远。哥特式建筑使用的飞扶壁上往往刻有沟让水沿飞扶壁流出。

滴水嘴兽的英语名称这个词来自于法语中的gargouille，意思是“喉咙”或者“阴沟”，其词根是拉丁语中的gurgulio、gula或gargula（阴沟或者喉咙）。与此相关的还有法语中的gargariser（漱口）。意大利语中的doccione或者gronda sporgente是建筑学比较精确的词，意为“伸出的水管”。德语的Wasserspeier和荷兰语的waterspuwer意为“喷水者”。

In architecture, a gargoyle (/ˈɡɑːrɡɔɪl/) is a carved or formed grotesque with a spout designed to convey water from a roof and away from the side of a building, thereby preventing rainwater from running down masonry walls and eroding the mortar between. Architects often used multiple gargoyles on buildings to divide the flow of rainwater off the roof to minimize the potential damage from a rainstorm. A trough is cut in the back of the gargoyle and rainwater typically exits through the open mouth. Gargoyles are usually an elongated fantastic animal because the length of the gargoyle determines how far water is thrown from the wall. When Gothic flying buttresses were used, aqueducts were sometimes cut into the buttress to divert water over the aisle walls.
