花腔（意大利语：Coloratura）是一种华丽的演唱技巧，主要应用于西洋古典音乐中，以装饰音多而难度大而著名。起源于17-18世纪的意大利阉伶，现在多由女高音或次女高音演唱。

Coloratura (Italian pronunciation: [koloraˈtuːra]) has several meanings: The word is originally from Italian, literally meaning "coloring", and derives from the Latin word colorare ("to color"). When used in English, the term specifically refers to elaborate melody, particularly in vocal music and especially in operatic singing of the 18th and 19th centuries, with runs, trills, wide leaps, or similar virtuoso-like material. Its instrumental equivalent is ornamentation. It is also now widely used to refer to passages of such music, operatic roles in which such music plays a prominent part, and singers of these roles. (See also bel canto.)
