Infiniti (Japanese: インフィニティ, Infiniti^?) is the premium or luxury-type division of Japanese automaker Nissan Motors. Infiniti officially started selling vehicles on November 8, 1989 in North America. Marketing operations have since grown to include the Middle East, South Korea, Russia, Taiwan, China, and Ukraine. Infiniti began sales in additional European markets in late 2011. The marketing network for Infiniti-branded vehicles now includes over 230 dealers in over 15 countries.^{[citation needed]}

The marque is not used in Japan and the automaker markets most of equivalent Infiniti models domestically as Nissans: Infiniti G as the Nissan Skyline sedan and coupe, Infiniti M as the Nissan Fuga, Infiniti EX as the Nissan Skyline crossover, and Infiniti Q45 as the Nissan Cima. The Infiniti FX has no Nissan equivalent and is not sold in Japan
