Many regiments have over the years earned nicknames; some laudatory, some derogatory, but all colourful. Sometimes, the nicknames themselves have overshadowed the actual regimental title, e.g. the "Van Doos" for the Royal 22<sup>e</sup> Régiment. In some cases the nickname actually replaced it: in 1881, the 42nd (Royal Highland) Regiment of Foot became officially known by its nickname, The Black Watch.
What follows is a list of nicknames of Canadian regiments, arranged alphabetically by regimental title. A brief explanation of the origin of the nickname, where known, is included.
