The Juno Award for Breakthrough Group of the Year is presented by the Canadian Academy of Recording Arts and Sciences to the best new musical group in Canada.
The award has been given annually since 1974, and was previously called Most Promising Group of the Year (1974–1993), Best New Group (1994–2002), and New Group of the Year (2003–2012).
The award was customarily presented by the Minister of Canadian Heritage.
The award was discontinued following the Juno Awards of 2024.
At the following Juno Awards of 2025, it was merged with the sibling category for Breakthrough Artist of the Year into a single category for Breakthrough Artist or Group of the Year.
