巴比伦空中花园（古希腊文：οἱ [τῆς Σεμιράμιδος] Κῆποι Κρεμαστοὶ Βαβυλώνιοι）是古代世界七大奇迹之一，又称悬园。在前6世纪由新巴比伦王国的尼布甲尼撒二世（Nebuchadnezzar）在巴比伦城为其患思乡病的王妃安美依迪丝（Amyitis）修建的。现已不存，也是目前唯一一个位置尚未明确得知的遗迹。

空中花园据说采用立体造园手法，将花园放在四层平台之上，由沥青及砖块建成，平台由25米高的柱子支撑，并且有灌溉系统，奴隶不停地推动连系着齿轮的把手。园中种植各种花草树木，远看犹如花园悬在半空中。

The Hanging Gardens of Babylon, one of the Seven Wonders of the Ancient World, is the only one whose location has not been definitively established.

The Hanging Gardens were a distinctive feature of ancient Babylon. They were a great source of pride to the people. Possibly built by King Nebuchadnezzar II in 600 BC, the gardens are believed to have been a remarkable feat of engineering: an ascending series of tiered gardens containing all manner of trees, shrubs, and vines. The gardens were said to have looked like a large green mountain constructed of mud bricks.
