Oberstabsbootsmann[1] (OStBtsm or OSB) is the highest Non-commissioned officer (NCO) rank in the German Navy. It is grouped as OR9 in NATO, equivalent to an Sergeant Major in the United States Navy, and an Warrant Officer Class 1 in the British Royal Navy

In navy context NCOs of this rank were formally addressed as Herr Oberstabsbootsmann also informally / short Oberstaber.

The rank was introduced in the German Navy equivalent to the German Heer and German Luftwaffe grad Oberstabsfeldwebel in 1995, and belongs to the grad group Unteroffiziere mit Portepee.
