铁琴（metallophone）可以指一些以金属制作的、有音高的乐器，通常可以透过不同类型的琴棒敲击铁片发出各种不同的声音。例如，用硬棒敲击可以发出清脆、响亮的声音。用软棒敲击可以发出绵延、柔软的声音。

可称为铁琴的常见乐器如下：

• 钢片琴（celesta）
• 铁片琴（glockenspiel）
• 颤音琴（vibraphone）

A metallophone is any musical instrument consisting of tuned metal bars which are struck to make sound, usually with a mallet.

Metallophones have been used in music in Asia for thousands of years. There are several different types used in Balinese and Javanese gamelan ensembles, including the gendér, gangsa and saron. These instruments have a single row of bars, tuned to the distinctive pelog or slendro scales, or a subset of them. The Western glockenspiel and vibraphone are also metallophones: they have two rows of bars, in an imitation of the piano keyboard, and are tuned to the chromatic scale.
