Department of Islamic Development Malaysia or popularly known as JAKIM (جاكيم), is a federal government agency in Malaysia that administers Islamic affairs in Malaysia.

Islam in Malaysia is represented by the Shafi‘i school of Sunni jurisprudence. Islam was introduced to Malaysia by traders arriving from Persia, Arabia, China and the Indian subcontinent. It became firmly established in the 15th century. In the Constitution of Malaysia, Islam is granted the status of "religion of the Federation" to symbolize its importance to Malaysian society, while defining Malaysia constitutionally as a secular state. Therefore, other religions can be practiced legally, though freedom of religion is still limited in Malaysia.
