'Bienenhaus' was a German and Croat pair of operations ('Bienenhaus I' and 'Bienenhaus II') against the partisan forces of Marshal Josip Broz Tito in the Moslavačka mountain region in German-occupied Yugoslavia by elements of General Dr Julius Ringel’s (from 24 June General Helge Auleb’s) LXIX Corps (25/30 June 1944).

Undertaken against the units of the 33^rd Division, the two offensives were the responsibility of the 1^st Reiterregiment 'Don', 4^th Reiterregiment 'Kuban' and 55^th Aufklärungsabteilung of Generalleutnant Hellmuth von Pannwitz’s 1^st Kosaken-Kavalleriedivision, and Pukovnik Stjepan Peričić's 1^st Mountain Brigade and Pukovnik Rafael Boban’s 5^th Active Service Brigade of the Croat home defence army, supported by German military police detachments.

'Bienenhaus I' took place in the area of Cazma on 25/27 June, ending after the 33^rd Division had escaped the net intended to trap it, and 'Bienenhaus II' followed on 29/30 June after the Axis forces had regrouped in the area of Ivanic-Grad, and also ended in failure. The 1^st Mountain Brigade lost six men killed and 18 wounded, and the 33^rd Division eight men killed, 50 wounded and 70 missing.
