塔勒（Thaler、Taler或Talir），或译为泰勒，一种曾在几乎整个欧洲使用了四百多年的银币名称及货币单位。

词源上，“塔勒”（Thaler）一词是银币类型“约阿希姆斯塔勒尔”（Joachimsthaler）的缩写，该银币类型是以波希米亚城市亚希莫夫的德语名“约阿希姆斯塔尔”（Joachimsthal）命名的，该类型的银币是亚希莫夫于1518年最早开始铸造的。在德语中，“Thal”意为“山谷”，“Thaler”意为来自山谷的人或事物，1902年德语拼写改革后，两词分别变为“Tal”和“Taler”，但英语中保持了“Thaler”的写法。“托拉尔”（Tolar）是塔勒在捷克语中的拼法。

The thaler was a silver coin used throughout Europe for almost four hundred years. Its name lives on in the many currencies called dollar and until recently, also the Slovenian tolar.

For the first time the name "thaler" was used as an abbreviation of "Joachimsthaler", a coin type from the town of Joachimsthal in the Kingdom of Bohemia, where silver mines were opened and the first such coins minted in 1518. The original Czech thaler carried a lion, the Czech coat of arms (of the Kingdom of Bohemia) on its reverse side as well as the Dutch daalders, the leeuwendaalder ("lion thaler"). From there, the name of the Balkan countries currencies (Romanian, Moldovan Leu and Bulgarian Lev).
