The following list shows the recipients for the Country Music Association Award for Vocal Group of the Year.[1] The award is based on the musical performance of the group on solo country single or album release, as well as their overall contribution to country music during the eligibility period. For the purposes of the award, a group is defined as "as an act composed of three or more people, both of whom normally perform together and none of whom are known primarily as individual performing artists", though this was not always the case.[2] In 1970, a separate category was established for vocal duos.
