An industrial musical is a musical performed internally for the employees or shareholders of a business to create a feeling of being part of a team, to entertain, and/or to educate and motivate the management and salespeople to improve sales and profits. It can be used to increase staff awareness of public relations, advertising, marketing or corporate image.

Other terms for industrial musicals include the corporate musical or industrial show, but the latter can also refer to trade shows, which are publicity events organized by businesses in a specific industry to promote their products to potential buyers.

Industrial musicals are not restricted to corporations or to businesses involved in industry. They should not be confused with industrial music or with musicals produced by businesses to be seen by the general public, such as Disney's stage production of The Lion King, for example.
