Regional geography is the study of world regions. Attention is paid to unique characteristics of a particular region such as natural elements, human elements, and regionalization which covers the techniques of delineating space into regions.

Regional geography is also a certain approach to geographical study, comparable to quantitative geography or critical geography. This approach prevailed during the second half of the 19th century and the first half of the 20th century, a period when then regional geography paradigm was central within the geographical sciences. It was later criticised for its descriptiveness and the lack of theory. Strong criticism was leveled against it in particular during the 1950s and the quantitative revolution. Main critics were G. H. T. Kimble and Fred K. Schaefer.

The regional geography paradigm has had an impact on many other geographical sciences, including economic geography and geomorphology. Regional geography is still taught in some universities as a study of the major regions of the world, such as Northern and Latin America, Europe, and Asia and their countries. In addition, the notion of a city-regional approach to the study of geography gained some credence in the mid-1990s through the work of geographers such as Saskia Sassen, although it was also criticized, for example by Peter Storper.
