This is a list of countries in which Islam is the majority religion of the people. In a geopolitical sense these countries are often considered to form the Muslim world. The list contains only countries where more than 50% of the population is Muslim. The table is presorted by the largest population by country. It can be sorted on other criteria by clicking the tab of the appropriate column at the top of the table. The percentage shows the proportional amount of Muslims out of the total population of each country. In total, there are about 50 Muslim-majority countries, depending on a few disputed states.

The table is currently sorted by the total population but can be sorted in various ways. The Muslim % column is the percentage of Muslims of a country out of the total population. The higher the percentage is of a country, then the higher the Muslim majority. Mauritania, Maldives, Saudi Arabia and Somalia have the highest Muslim percentages with 100% of their countries population as Muslims. For the Maldives and Saudi Arabia this figure only applies to citizens of the respective countries. The foreign workers are excluded from this count; there are no official statistics available regarding the exact number of foreign workers in either of these two countries.
