Henrico County /hɛnˈraɪkoʊ/, officially the County of Henrico, is a county located in the Commonwealth of Virginia in the United States. As of the 2020 census, the population was 334,389 making it the fifth-most populous county in Virginia. Henrico County is included in the Greater Richmond Region. There is no incorporated community within Henrico County; therefore, there is no incorporated county seat either. Laurel, an unincorporated CDP, serves this function.
Named after the settlement of Henricus, Henrico was first incorporated as the City of Henrico. In 1634, Henrico was reorganized as Henrico Shire, one of the eight original Shires of Virginia. It is one of the United States' oldest counties. The City of Richmond was officially part of Henrico County until 1842, when it became a fully independent city.
