The 28th (Maori) Battalion, more commonly known as the Maori Battalion, was an infantry battalion of the New Zealand Army that served during the Second World War.

Raised in 1940 as part of the Second New Zealand Expeditionary Force, the battalion fought during the Greek, North African and Italian campaigns during which it earned a formidable reputation as a fighting force which has subsequently been acknowledged by both Allied and German commanders.

It was also the most decorated New Zealand battalion during the war. Following the end of hostilities, the battalion contributed a contingent of personnel to serve in Japan as part of the British Commonwealth Occupation Force, before being disbanded in January 1946.
