The Unova region (Japanese: イッシュ地方 Isshu-chihō) is a large area of the Pokémon world and the setting of the fifth generation Pokémon games Pokémon Black and White. It is far away from the four other large regions, and the Pokémon which inhabit Unova are diverse and different from those of Kanto, Johto, Hoenn, and Sinnoh. In his director's column, Junichi Masuda suggested that the geographical and social background for Unova draws inspiration from the New York City metropolitan area[1], although the region features rural locations as well as industrial.

Unova features fifteen settlements which reflect the diversity of the region. Hiun City, a sprawling metropolis, is the largest city in any known Pokémon region. Kanoko Town, which is inhabited by the Pokémon expert Professor Araragi, is smaller and quieter. Black City is a version-exclusive city found only in Pokémon Black. Unova's landscape also features several forests (one of which, White Forest, is also version-exclusive), a desert, a magnetic cave and areas where the move Dive can be used outside of battle. Although Unova appears in some ways more technologically advanced than the previous regions, this development is not spread across the whole of the region.

These towns and cities are connected by a network of routes. These are numbered from 1 to 18, mimicking the naming scheme used in Kanto and emphasizing Unova's isolation. Unova has the least numbered routes of any region, but also has named routes stretching between settlements. These include five bridges and a subway network.

Unlike previous regions, where climatic change was experienced locally (that is to say, some routes would always feature snow, and some routes would always feature rain), Unova is susceptible to national seasonal change. Spring, summer, autumn and winter each last approximately thirty days, and recur three times each within a year. Each season brings with it different weather patterns, unlocks different events, and presents altered Pokémon availabilities
