The Meritorious Service Cross is a decoration that is, within the Canadian system of honours, one of the two Meritorious Service Decorations gifted by the Canadian monarch, his or her Governor-in-Council. Created in 1984, the medal is intended to recognize individuals—both Canadian and foreign—who have carried out meritorious acts bringing benefit and honour in either of two categories: military and civilian.

The orders, decorations, and medals of Canada comprise a complex system by which Canadians are honoured by the country's sovereign for actions or deeds that benefit their community or the country at large. Modelled on its British predecessor, the structure originated in the 1930s, but began to come to full fruition at the time of Canada's centennial in 1967, with the establishment of the Order of Canada, and has since grown in both size and scope to include dynastic and national orders, state, civil, and military decorations; and various campaign medals. The monarch in right of each Canadian province also issues distinct orders and medals to honour residents for work performed in just their province. The provincial honours, as with some of their national counterparts, grant the use of post-nominal letters and or supporters and other devices to be used on personal coats of arms.
