List of diplomatic missions of Austria-Hungary

This is a list of diplomatic missions of Austria-Hungary from the formation of the Dual Monarchy in 1867 until its dissolution in 1918Foreign affairs were administered as a common institution of the Dual Monarchy under the k.u.k. (kaiserlich und königlich, "Imperial and Royal") Ministry of Foreign Affairs, headquartered in Vienna. Under the terms of the 1867 Ausgleich, foreign policy was conducted jointly for both Cisleithania (Austria) and Transleithania (Hungary)

Austria-Hungary maintained diplomatic representation in Europe, the Americas, Asia, and the Near East. Most missions were legations headed by envoys extraordinary and ministers plenipotentiary rather than ambassadors, reflecting the diplomatic hierarchy of the period. In several cases, a single minister was concurrently accredited to multiple states, particularly in Latin America and among the German states

At its height, the monarchy maintained ministers in 39 states. Following the dissolution of Austria-Hungary in 1918, its diplomatic missions were either closed or transferred to the successor states, principally Austria and Hungary.
