The Mitsubishi Pajero (IPA: /pəˈhɛroʊ, pɑˈxɛroʊ/) is a sport utility vehicle manufactured by Mitsubishi Motors. It was named after Leopardus pajeros, the Pampas Cat which inhabits the Patagonia plateau region in southern Argentina.However, because pajero is a slang term for "wanker" in the Spanish language alternative names have been adopted for certain overseas markets. It is known as the Mitsubishi Montero (meaning "mountain warrior") in Spain, India, and the Americas (except Brazil), and as Mitsubishi Shogun in the United Kingdom.

Thanks to their success, the Pajero, Montero and Shogun names were also applied to other, mechanically unrelated models, such as the Pajero Mini kei car, the Pajero Junior and Pajero iO/Pinin mini SUVs, and the Mitsubishi Pajero/Montero/Shogun Sport.
