The Islamic Society in Finland was established in 1986 and was registered at the beginning of 1987 as the second official Islamic religious society in Finland. The registration was made with the approval of the Ministry of Education based on the Finnish Freedom of Religion Act of 1923.

Every Muslim man or woman residing in Finland can join the society, regardless of their original language. Membership continues even if the resident changes his place of residence unless he resigns. In 2020, the Society is considered the second-largest Islamic society in Finland, which includes Muslims of all ethnic and linguistic backgrounds, in addition to Muslims of Finnish origins. The majority of the society’s members hold Finnish citizenship. The society is a founding member of the Finnish Islamic Council.
