Freedom of religion prevails and Christianity is the dominant religion. The largest individual community is the Anglican Church, which comprises around one-third of the population.

The Methodist Church is almost as large. Other Protestant communities such as Hussites and Baptists are also represented. Around eight percent of residents are Catholics. There is also a group of Orthodox Christians as well as some rastafari (see Jamaica, religion).

Religion is an important unifying force in society and permeates the culture of the islands. Some, especially older people but also some younger ones, confess to the folk religion obeah, which has roots in Africa. Obeah has some similarities to voodoo and is based, among other things, on the assumption that a person can use supernatural forces to harm someone else.
