云门（Cloud Gate，因其外形又被俗称为“豆荚”（the Bean））是一件由英国艺术家阿尼什·卡普尔所设计的公共艺术塑像作品，位于美国伊利诺伊州芝加哥卢普区千禧公园的AT&T广场内，大通长廊（Chase Promenade）与麦考密克中心论坛广场与溜冰场（McCormick Tribune Plaza & Ice Rink）之间，建造于2004年6月至2006年5月。这一作品长20米，宽13米，高10米，拱底最高处距地面约4米，重100吨。云门虽由168块不锈钢板接焊而成，但其表面非常光滑，游客可以在其上看到被反射和扭曲的城市轮廓，但完全观察不到接缝。此外，塑像的底部为会歪曲和重叠影像的凹形空间，被称为“omphalos”（希腊语意为“中央”）。
