Litochoro is a town and a former municipality in the southern part of the Pieria regional unit, Macedonia, Greece. Since the 2011 local government reform it has been part of the Dio-Olympos municipality, of which it is the seat and a municipal unit. It is located at the base of Mount Olympus, on the western shore of the Thermaic Gulf. The first recorded mention of Litochoro is in an account of a visit by Saint Dionysius to Mount Olympus in the 16th century. The town is a popular destination for those wishing to climb Mount Olympus as almost all climbing routes begin to the southwest of the town. One of the most famous Litohorians was Christos Kakkalos, who made the first modern unaided ascent of Mount Olympus in 1913.

Mount Olympus is the highest mountain in Greece. It is part of the Olympus massif near the Thermaic Gulf of the Aegean Sea, located in the Olympus Range on the border between Thessaly and Macedonia, between the regional units of Larissa and Pieria, about 80 km (50 mi) southwest from Thessaloniki. Mount Olympus has 52 peaks and deep gorges. The highest peak, Mytikas, meaning "nose", rises to 2,917.727 metres (9,572.60 ft). It is one of the highest peaks in Europe in terms of topographic prominence.
