在约翰·罗纳德·鲁埃尔·托尔金（J.R.R. Tolkien）的奇幻小说世界中土大陆中，风云顶（Weathertop）是伊利雅德 Eriador境内的一座小山，是风云丘（Weather Hills）最高且最南端的山。

风云顶于辛达林语 Sindarin中被称为阿蒙苏尔（Amon Sûl，又译阿蒙苏、苏尔山），意思是「风的山丘」Hill of Wind。在北方王国亚尔诺 Arnor的历史上，风云顶占有颇重要的地位。因为风云顶曾是王国的重要前线要塞、一枚真知晶石 Palantír的存放点及几场重要战役的发生处。

In the works of J. R. R. Tolkien, Weathertop (Sindarin Amon Sûl, "Hill of Wind") is a hill in the Eriador region of Middle-earth, the southernmost and highest summit of the Weather Hills. The hill itself is of great importance in the history of Middle-earth, as chronicled in The Lord of the Rings, since it was a major fortress of the kingdom of Arthedain, home to one of the seven palantíri, and the site of several battles.
