Das Ehren- und Erinnerungskreuz des Marinekorps Flandern (Honor and Remembrance Cross of the Navy Corps, Flanders) also referred to as "Flandernkreuz". This was a non-official decoration awarded during the Weimar Republic, most likely as a commemorative token to members of the Navy Corps stationed on the Flemish coast in Belgium.

This bronze cross has crossed swords between the cross's arms and has on the obverse a central medaillon with, within a laurel wreath, an anchor on the letter "W" (Emperor Wilhelm) and an emperor's crown on top. The cross's arms bear the text "Zur See / Unbe- / siegt / Im Felde" which should be read : Zur See, Im Felde, unbesiegt (on the seas, in the field, unvanquished).

The reverse has the "Kriegsflagge", the German Navy Battle Flag, in the laurel wreathed medaillon and a Flemish lion in the upper cross arm. The remaining arms have the text "MARINE- / KORPS - 1914/18". The ribbon is in the then German national colours.
