Katzianer's Campaign or Katzianer's War (Croatian: Katzianerova vojna) was a failed 1537 Habsburg attempt of driving the Ottomans away from the region of Slavonia in modern-day Croatia. Despite being well-resourced, Katzianer's army failed to achieve any objectives, and it was ultimately completely annihilated in the Battle of Gorjani.
