Jamaat-e-Islami, or Jamaat as it is commonly known, is an Islamist political party based in Pakistan and founded by Abul Ala Maududi. It is the Pakistani successor to Jamaat-e-Islami, which was founded in colonial India in 1941. Its objective is the transformation of Pakistan into an Islamic state, governed by Sharia law, through a gradual legal, and political process. JI strongly opposes capitalism, communism, liberalism, and secularism as well as economic practices such as offering bank interest. JI is a 'vanguard party', whose members are intended to be leaders spreading party beliefs and influence. Supporters not thought qualified to be members may become 'affiliates', and beneath them are 'sympathizers'. The party leader is called an 'ameer'. Although it does not have a large popular following, the party is quite influential and considered one of the major Islamic movements in Pakistan, along with Deobandi and Barelvi.

Islamism is a religio-political ideology. The advocates of Islamism, also known as "al-Islamiyyun", are dedicated to realizing their ideological interpretation of Islam within the context of the state or society. The majority of them are affiliated with Islamic institutions or social mobilization movements, often designated as "al-harakat al-Islamiyyah." Islamists emphasize the implementation of sharia, pan-Islamic political unity, the creation of Islamic states,, and rejection of non-Muslim influences—particularly Western or universal economic, military, political, social, or cultural.
