อิสลามในอินโดนีเซีย

Islam is the most adhered to religion in Indonesia, with 87.2% of Indonesian population identifying themselves as Muslim in 2010 estimate. Indonesia has the largest Muslim population in the world, with approximately 225 million Muslims.

In terms of denomination, absolute majority (99%) adheres to Sunni Islam, while there are around one million Shias (0.5%), who are concentrated around Jakarta, and about 400,000 Ahmadi Muslims (0.2%). In terms of Islamic schools of jurisprudence, based on demographic statistics, 99% of Indonesian Muslims mainly follow the Shafi'i school, although when asked, 56% does 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 syncretic form of Islam known as kebatinan.

Islam in Indonesia is roughly considered to have gradually spread through merchant activities by Arab Muslim traders, adoption by local rulers and the influence of mysticism since the 13th century. During the late colonial era, it was adopted as a rallying banner against colonialism. Today, although Indonesia has an overwhelming Muslim majority, it is not an Islamic state, but constitutionally a secular state whose government officially recognizes six formal religions.
