Midem is the acronym for Marché International du Disque et de l'Édition Musicale, which is organised annually in and around the Palais des Festivals et des Congrès in Cannes, France. The trade show, organized by Reed MIDEM, a subsidiary of Reed Exhibitions, is billed as the leading international business event for the music ecosystem and has been held since 1967. Several thousand musicians, producers, agents, managers, lawyers, executives, entrepreneurs and journalists from around the globe regularly attend the event, which is usually held at the end of January or early February. While delegates from recording, artist management, and publishers network, new artists showcase their material. Also live music is on show in the evenings.

The event is developing like the industry and is now focused on the core music business (labels, publishers, rights societies and more), the technology sector (startups, developers and big tech companies), and brands and the agencies that represent them (for music and brand campaigns). Since 2007, the Midemlab competition for companies working in musictech has grown in importance. SoundCloud, Spotify and Songkick are among the companies that have risen to prominence after showcasing there.

In December 2021, RX France - the organisers of Midem - made an announcement that they were cancelling the 2022 edition. A statement on their website stated simply, "Due to the lasting pandemic and following a review of its activity, RX France has decided to no longer continue to organize the Midem event." In a separate communication, Midem Director Alexandre Deniot announced that RX France and the city of Cannes were in "exclusive and advanced discussions for the latter to take over the Midem brand".
