庆熙宫是李氏朝鲜时代的宫殿，位于大韩民国首尔市。

朝鲜王朝的正宫景福宫和离宫昌德宫、昌庆宫在壬辰倭乱中被焚毁，宣祖不得不以月山大君府第（庆运宫）为临时行宫。光海君即位后，一边修复昌德宫和昌庆宫，一边下令在王气较旺盛的仁王山脚下兴建新宫，即庆熙宫的前身庆德宫。同一时期还为宣祖的继妃仁穆大妃修建了仁庆宫。

庆德宫在万历四十四年(1616年)建成。由于位于正宫景福宫（北阙）的西侧，因此称为「西阙」。在光海君至哲宗时期，庆德宫与东阙昌德宫是朝鲜王朝的两座主要宫殿。英祖年间，庆德宫改名为庆熙宫。

庆熙宫的正门为兴化门，内门为建明门，正殿为崇政殿，外为崇政门，便殿为资政殿，国王寝殿为隆福殿，王妃寝殿为会祥殿、此外还有集祥殿、集庆堂、兴政堂、德游堂、景贤堂等建筑。孝宗五年为了在昌德宫内给慈懿大妃修建万寿殿，曾拆除庆德宫的钦敬阁、齐政堂、丕显阁、观文阁、协和楼、承晖楼、鱼藻堂、万祥楼等建筑，用拆下来的木料在昌德宫里建造了万寿殿和春晖殿。庆熙宫曾与离宫庆运宫(德寿宫)有虹桥（复道）相连。

Gyeonghui Palace (in Korean: Gyeonghuigung, literally Palace of Serene Harmony) was a palace located in Seoul, South Korea. It was one of the "Five Grand Palaces" built by the Joseon Dynasty.

Construction began in the 1600s during the reign of King Gwanghaegun. In the latter Joseon period, Gyeonghuigung served as the secondary palace for the king, and as it was situated on the west side of Seoul, it was also called Seogwol (a palace of the west). The Secondary palace is usually the palace where the King moves to in times of emergency.
