This is a list of notable reggae festivals by country.

Reggae originated in Jamaica in the late 1960s, influenced by Rastafarian culture, Jamaican dance music, traditional mento and calypso music, as well as American jazz and rhythm and blues, and evolved out of the earlier genres ska and rocksteady.

By the 1970s, large festivals in Jamaica were being held featuring notable reggae bands, and the Wonder Dream Concert in 1975 in Jamaica was one of the first internationally noted festivals to focus on reggae.

In 1979, Reggae Geel became the first reggae festival in Europe, and these concerts soon spread to other locales, becoming popular in regions such as Northern California.

With the introduction of the electronic reggae genre ragga in the 1980s, reggae began to be featured at electronic music festivals as well.
