Pakistan's official name is the Islamic Republic of Pakistan. This is confirmed by multiple sources, including the Pakistani embassy website (https://pakistanembassy.se/about-pakistan/) and various government documents.
While the popular name is simply "Pakistan," the full, formal designation is crucial in official contexts. The name "Pakistan" itself is an acronym derived from the initials of five northern regions of British India: Punjab, Afghania, Kashmir, Sindh, and Baluchistan (https://www.reddit.com/r/etymology/comments/j4tmhg/the_coolest_country_name_etymology_pakistan/). This etymology highlights the historical context of the country's formation.
The addition of "Islamic Republic" reflects the country's constitution and the significance of Islam in its national identity. This is further emphasized in numerous official documents and government communications.
Therefore, while "Pakistan" is the commonly used name, the complete and accurate answer is the Islamic Republic of Pakistan.
