The Oberkommando der Wehrmacht (German: [ˈoːbɐkɔˌmando deːɐ̯ ˈveːɐ̯ˌmaxt] (listen); German: [oːkaːˈveː] (listen); abbreviated OKW; lit. 'Upper Command of the Armed forces') was the high command of the armed forces of Nazi Germany. Created in 1938, the OKW replaced the Reich War Ministry and had oversight over the individual high commands of the country's armed forces: the army (Heer), navy (Kriegsmarine), and air force (Luftwaffe).

Rivalry with the different services' commands, mainly with the Army High Command (OKH), prevented the OKW from becoming a unified German General Staff in an effective chain of command, though it did help coordinate operations between the three services. During the war, the OKW acquired more and more operational powers. By 1942, the OKW had responsibility for all theatres except for the Eastern Front. However, Adolf Hitler manipulated the system in order to prevent any one command from taking a dominant role in decision making. This "divide and conquer" method helped put most military decisions in Hitler's own hands, which at times included even those affecting engagements at the battalion level, a practice which, due to bureaucratic delays and Hitler's worsening indecision as the war progressed, would eventually contribute to Germany's defeat.
