The Ahmadiyya Muslim Community is the second-largest sect of Islam in Sierra Leone, behind only Sunni Islam. The earliest history of the Community in Sierra Leone dates back to the early period of the Second Caliphate, when at least six people are said to have conveyed their adherence to the faith. The sect attained rapid growth in the country after the 1937 arrival of Nazir Ahmad Ali, the first permanent Ahmadi missionary in Sierra Leone. Recent estimates by Ahmadi community suggest that there are approximately 560,000 Ahmadi Muslims in Sierra Leone, which is about 9% of the country's total population. Sierra Leone has the largest percentage of Ahmadi Muslims by share of total population in the world.
