The Microvision Song Festival, sometimes popularly called Microvision, is the longest-running micronational annual international TV song competition, held, primarily, among the member countries of the Micronational Broadcasting Union (UMR-MBU) since 2015.

Each participating country submits an song to be and then casts votes for the other countries' songs to determine the most popular song in the competition. The contest has been broadcast every year for two years, since its inauguration in 2015.
