铙钹（法语：Crotales（读作 "kro-tah'-les"），英语：Crotales，又可称为 antique cymbals），是一种有固定音高的西洋敲击乐器。

铙钹是一件相当古老的乐器。远在公元前12世纪已经存在。爱尔兰国家博物馆内收藏了多件介于青铜时期(公元前1200-800)的古代乐器，当中便包括了一组类似铙钹的乐器。铙钹其实是一种以手指来击奏的踫钹，由两块小铜片，压成碗形而成，后期后来则由碗形再演变成两片稍为弯曲的铜板。大英博物馆现时收藏有一套约公元前五世纪于希腊发掘出来的碗形铙钹，以及数个在公元前四世纪的机械式铙钹，它的外形有如一个夹子，两端尾部装上了一片的小钹片，当按压夹子时，借此令小钹踫撞而发声。另外埃及的出士文物也发现过一套四款的铙钹，分别安装在四支固定的金属柄上。。

Crotales (/kroʊˈtɑːleɪz/), sometimes called antique cymbals, are percussion instruments consisting of small, tuned bronze or brass disks. Each is about 4 inches in diameter with a flat top surface and a nipple on the base. They are commonly played by being struck with hard mallets. However, they may also be played by striking two disks together in the same manner as finger cymbals, or by bowing. Their sound is rather like a small tuned bell, only with a much brighter sound, and a much longer resonance. Like tuned finger cymbals, crotales are thicker and larger; they also have slight grooves in them which give their sound more sparkle. The name comes from the Greek crotalon, for a castanet or rattle.
