'Hagen' (i) was a German series of 91 convoys in the Black Sea to deliver reinforcements, equipment and supplies to Generaloberst Richard Ruoff’s (from 24 June Generaloberst Erwin Jaenecke’s) 17^th Army in the Kuban beach-head across the Strait of Kerch from eastern Crimea (1 June/20 September 1943).

The effort was later supplemented by the 'Bansin' convoys from Feodosiya to Anapa, and was based largely on the use of 13 naval ferry barges of Kapitänleutnant Max Giele’s 1^st Landungs-Flottille, Fregattenkapitän Gustav Strempel’s 3^rd Landungs-Flottille and Korvettenkapitän Carl Mehler’s 5^th Landungs-Flottille, bolstered by varying numbers of tugs and lighters.
