{{lang|de|Linienschiffsleutnant}} ({{translation|Ship-of-the-line lieutenant}}; {{langx|hu|Sorhajóhadnagy}}) was an officer rank in the Austro-Hungarian Navy. It was equivalent to {{lang|de|Hauptmann}} of the Austro-Hungarian Army, as well to {{lang|de|Kapitänleutnant}} of the Imperial German Navy.
The rank designation was used continuously in the Austria-Hungarian follow on countries Yugoslavia, Croatia, and Slovenia, as well as in the modern day's Austrian merchant navy.
The rank name was selected in line to the division of war ships to specific ship categories early of the 19th century, e.g. corvette ({{lang|de|Korvette}}), frigate ({{lang|de|Fregatte}}), and to ship of the line ({{lang|de|Linienschiff}}). In the Austro-Hungarian Navy the appropriate rank designations were derived as follows.
According to that systematic the rank designations to subaltern – or junior officers were derived as follows:
- Linienschiffsleutnant equivalent to Hauptmann
- Fregattenleutnant equivalent to Oberleutnant
- Korvettenleutnant equivalent to Leutnant
