Groschen is the name for various coins, especially a silver coin used in parts of Europe such as France, some of the Italian states, England, various states of the Holy Roman Empire, among others. The word is borrowed from the late Latin description of a tornose, a grossus denarius Turnosus, in English the "thick denarius of Tours". Groschen was frequently abbreviated in old documents to gl, whereby the second letter was not an l, but an abbreviation symbol; later it was written as Gr or g.

The groat is the traditional name of a defunct English and Irish silver coin worth four pence, and also a Scottish coin which was originally worth fourpence, with later issues being valued at eightpence and one shilling.
