Hartford County is a county located in the north central part of the U.S. state of Connecticut. According to the 2020 census, the population was 899,498, making it the second-most populous county in Connecticut. Hartford County contains the city of Hartford, the state capital of Connecticut and the county's most populous city, with 121,054 residents at the 2020 census. Hartford County is included in the Hartford-East Hartford-Middletown metropolitan statistical area.

On June 6, 2022, the U.S. Census Bureau formally recognized Connecticut's nine councils of governments as county equivalents instead of the state's eight counties. Connecticut's county governments were disbanded in 1960, and the councils of governments took over some of the local governmental functions. Connecticut's eight historical counties continue to exist in name only, and are no longer considered for statistical purposes.
