List of current longest ruling non-royal national leaders

This list of current longest ruling non-royal national leaders is a list of the current living longest ruling heads of nation-states or national governments, who are not royalty, and have served ten years or longer, sorted by length of tenure.

The individuals on the list are not always the most powerful figure in their country's national government. Some are or have been at one time but not necessarily continuously throughout the listed timespan. Some of them have held more than one national leadership level office: presidency, prime minister-ship, or some other title implying or widely believed to confer national leadership. When more than one such office exists in a country, there may be uncertainty as to which member of the national government actually has the ultimate power. Therefore, this list combines all national level offices held concurrently or consecutively by each individual leader.
