Hassanal Bolkiah, the current longest-reigning monarch

This article lists the monarchs who have been ruling their countries for the longest time. A monarch is a king, queen, sultan, or prince who is the head of a country. They usually inherit their position from their family.

This list includes monarchs who rule over entire nations or important parts of nations. It does not include former rulers, people who claim to be monarchs but don't actually rule, or leaders who are only monarchs because of another job they have. It also doesn't include traditional rulers who don't have official power over a country.
