Carolina is an urban-rural area situated at the intersection of the R33, R36 and R38 routes in the Mpumalanga province of South Africa.

The town lies in the grass and wetlands region of Mpumalanga at 1700 meters above sea level.

Carolina was established by Cornelius Johannes Coetzee as a permanent outspan for wagons when gold was discovered in 1883 in Barberton.

The sandstone Grobler Bridge which crosses the Komati River on the present R36 route to Machadodorp was opened for traffic in 1897.

The cornerstone of the Dutch Reformed Church was laid by Commandant General Piet Joubert in October 1888.
