Leutnant zur See is a military rank, used in a number of navies.

Leutnant zur See (Lt zS or LZS) is the lowest officer rank in the German Navy, grouped as OF1 in NATO.

In navy context officers of this rank were simply addressed as Herr Leutnant.

The rank has since been used by the Reichsmarine, the Kriegsmarine and the German Navy.

[2] In the Volksmarine the rank was originally used in the same way until the suffix zur See was dropped.
