The Karlovy Vary agglomeration (Czech: Karlovarská aglomerace) is the agglomeration of the city of Karlovy Vary and its surroundings in the Czech Republic. It was defined in 2020 as a tool for drawing money from the European Structural and Investment Funds and is valid in 2021–2027. The agglomeration also includes the towns of Sokolov and Ostrov and has a population of about 138,000.

The Karlovy Vary agglomeration was defined in 2020 by the Ministry of Regional Development of the Czech Republic for the purposes of the so-called Integrated Territorial Investment (ITI), which is a tool for drawing money from the European Structural and Investment Funds.^[1]

The territory was defined on the basis of a coefficient composed of three methods: integrated system of centres (i.e. delineation of commuting flows based on mobile operator data from 2019), time spent in core cities (based on mobile operator data from 2019) and residential suburbanization zones (based on statistics of realized housing construction and directional migration from the core of the agglomeration to suburban municipalities in the period 2009–2016). The scope of the territory is valid for the period 2021–2027.^[1][3]

The agglomeration includes 33 municipalities.^[3]
