Interfaith dialogue, also known as interreligious dialogue, refers to cooperative, constructive, and positive interaction between people of different religious traditions (i.e., "faiths") or spiritual or humanistic beliefs, at both the individual and institutional levels.

Throughout the world, there are local, regional, national and international interfaith initiatives; many are formally or informally linked and constitute larger networks or federations. These include organisations such as the United Religions Initiative, the Parliament of the World's Religions, and interfaith training institutions like OneSpirit Interfaith Foundation in the United Kingdom, which since 1996, has prepared interfaith ministers for community service, spiritual accompaniment, and inclusive ceremony.

Islam is the largest religion in Indonesia, with 87.06% of the Indonesian population identifying themselves as Muslims, based on civil registry data in 2023. In terms of denomination, the overwhelming majority are Sunni and non-denominational Muslims; the Pew Research Center estimates them as comprising ~99% of the country's Muslim population in 2011, with the remaining 1% being Shia, who are concentrated around Jakarta, and about 400,000 Ahmadi as well.

In terms of schools of jurisprudence, based on demographic statistics, 99% of Indonesian Muslims mainly follow the Shafi'i school, although when asked, 56% do not adhere to any specific school. Trends of thought within Islam in Indonesia can be broadly categorized into two orientations: "modernism", which closely adheres to orthodox theology while embracing modern learning, and "traditionalism", which tends to follow the interpretations of local religious leaders and religious teachers at Islamic boarding schools (pesantren). There is also a historically important presence of a syncretic form of Islam known as kebatinan.
