HMCS Moncton is a Kingston-class coastal defence vessel that has served in the Canadian Forces since 1998. Moncton is the ninth ship of her class. She is the second vessel to use the designation HMCS Moncton. The ship is assigned to Maritime Forces Atlantic (MARLANT) and is homeported at CFB Halifax.

The Kingston class consists of 12 coastal defence vessels operated by the Royal Canadian Navy. The class is the name for the Maritime Coastal Defence Vessel Project (MCDV). These multi-role vessels were built and launched from the mid- to late-1990s and are crewed by a combination of Naval Reserve and Regular Force personnel. The main mission of the vessels is to train reservists, coastal patrol, minesweeping, law enforcement, pollution surveillance and search and rescue duties. The multi-purpose nature of the vessels led to their mixed construction between commercial and naval standards. The Kingston class is split between the east and west coasts of Canada and regularly deploy overseas to West Africa, Europe, Central America and the Caribbean.
