The Kokoda Track campaign or Kokoda Trail campaign was part of the Pacific War of World War II. The campaign consisted of a series of battles fought between July and November 1942 in what was then the Australian Territory of Papua. It was primarily a land battle, between the Japanese South Seas Detachment under Major General Tomitarō Horii and Australian and Papuan land forces under command of New Guinea Force. The Japanese objective was to seize Port Moresby by an overland advance from the north coast, following the Kokoda Track over the mountains of the Owen Stanley Range, as part of a strategy to isolate Australia from the United States.

The Kokoda Track or Trail is a single-file foot thoroughfare that runs 96 kilometres (60 mi) overland – 60 kilometres (37 mi) in a straight line – through the Owen Stanley Range in Papua New Guinea (PNG). The track was the location of the 1942 World War II battle between Japanese and Allied – primarily Australian – forces in what was then the Australian territory of Papua.
