List of countries in the Own Americavision Song Contest

Fifty-eight countries have participated in the Own Americavision Song Contest since it started in 2017. The contest, organised by the Own American Broadcasting Association, is held between members of the Union. Broadcasters from different countries submit songs to the event, and cast votes to determine the most popular in the competition.

Participation in the contest is primarily open to all active member broadcasters of the OABA. To be an active member, broadcasters must be a member of the Own American Broadcasting Association. Eligibility to participate is determined by geographic inclusion within the Americas.

The number of countries participating each edition has grown steadily. A record 52 countries participated in the twelfth edition. As the number of contestants has risen, preliminary competitions have been introduced, to ensure that as many countries as possible get the chance to compete. In the twelfth edition, a quarter-final was introduced. The 5 lowest-placed countries from each semi-finals in the previous edition have to participate in the quarter-final.

Some countries, such as Antigua and Barbuda, Barbados, Canada, Costa Rica, Dominica, Guyana, Puerto Rico, Saint Vincent and the Grenadines and United States have entered most editions, while Saint Barthélemy and Turks and Caicos Islands have only entered once.
