The geographical regions of Turkey comprise seven regions (Turkish: bölge), which were originally defined at the country's First Geography Congress in 1941.^[1] The regions are subdivided into 31 sections (Turkish: bölüm), which are further divided into numerous areas (Turkish: yöre), as defined by microclimates and bounded by local geographic formations.

"Regions" as defined in this context are merely for geographic, demographic, and economic purposes and do not refer to an administrative division.
