Diplomatic rank is the system of professional and social rank used in the world of diplomacy and international relations. Over time it has been formalized on an international basis.

Until the early 19th century, each European nation had its own system of diplomatic rank. The relative ranks of diplomats from different nations had been a source of considerable dispute, made more so by the insistence of major nations to have their diplomats ranked higher than those of minor nations, to be reflected in such things as table seatings.

In an attempt to resolve the problem, the Congress of Vienna of 1815 formally established an international system of diplomatic ranks.

The four ranks within the system are:

As it turned out, this system of diplomatic rank created its own set of problems regarding the nations' precedence. The appropriate diplomatic ranks used would be determined by the precedence among the nations; thus the exchanges of ambassadors (the highest diplomatic rank) would be reserved among major nations, or close allies and related monarchies. In contrast, a major nation would probably send just an envoy to a minor nation, who in return would send an envoy to the major nation. As a result, the United States did not use the rank of ambassador until their emergence as a major world power at the end of the 19th century. Indeed, until the mid-20th century, the majority of diplomats in the world were of the rank of envoy.
