St. Johns County is a county in the northeastern part of the U.S. state of Florida. As of the 2020 United States Census, its population was 273,425. The county seat and largest incorporated city is St. Augustine. St. Johns County is part of the Jacksonville metropolitan area.

The county was established in 1821. It is one of the two original counties established after Florida was ceded to the United States, at the start of the Florida Territorial period, and corresponded roughly to the former colonial province of East Florida. It was named for the St. Johns River, which runs along its western border.

Today, St. Johns County primarily comprises residential bedroom communities for those who commute to Jacksonville. Tourism, primarily associated with St. Augustine and the many golf courses in the area, is the chief economic industry.

There is also an unincorporated community named Saint Johns in northwestern St. Johns County.
