Antalya Mayor Muhittin Bocek said the fire had started at four different points. He told Haberturk four neighbourhoods had been evacuated but there were no reports of casualties yet.
Authorities could not immediately say what caused the fire.
Agriculture Minister Bekir Pakdemirli said authorities were battling the flames with a firefighting plane, 19 helicopters, 108 vehicles and some 400 personnel.
Turkey's AFAD disaster agency said emergency teams from nearby provinces were also called into action, while authorities evacuated settlements near the forest.
Antalya, a popular destination for both foreign and local tourists, is known for its scorching summer heat. Bocek said the extreme heat and strong winds were fanning the fire as it swept through the pine forest.
The fire comes as Turkey battles with a series of disasters caused by extreme weather conditions in recent weeks.
Earlier this month, flash floods in the Black Sea provinces of Rize and Artvin damaged homes and property. The floods killed six people in Rize, according to AFAD.
