List of countries in the Online Music Song Contest (A-L)

183 countries participated in the Online Music Song Contest since it started. Winners of the contest have come from sixteen of these countries (Finland, France, Greece, Guadeloupe, Iceland, Kiribati, Kyrgyzstan, Norway, Poland, Portugal, Serbia, South Korea, Sweden, Switzerland, Ukraine, United Kingdom). The contest is held in the winning country of the previous edition. Broadcasters from different countries submit songs to the event and cast votes to determine the most popular in the competition.

The number of countries participating each edition has grown steadily, from 18 in OMSC 1 to around 50 in OMSC 15. In that occasion a record of 50 countries participated, while in OMSC 2 a record of just 14 countries participated, making it the edition with the smallest number of participants since the start of the contest so far. As the number of contestants has risen, preliminary competitions and relegation have been introduced, to ensure that as many countries as possible get the chance to compete.

After Canada's withdrawal from the contest in OMSC 15, the United States of America are the only country that has participated in every edition. Other countries like Bolivia, Czechia and India have only entered once. Some countries, such as Yemen and Mozambique, have attempted to enter the contest but withdrew before making a debut.
