The province of Reggio Calabria was located at the extreme southern tip of mainland Italy.
To the west lies the Tyrrhenian Sea and to the south and southeast lies the Ionian Sea.
The land borders are short; to the northeast lies the province of Catanzaro and to the northwest, the province of Vibo Valentia.
Across the Strait of Messina, some 3 kilometres (1.9 mi) to the southwest, lies the island of Sicily.

The province can be divided into three types of terrain.
Near the west it is mountainous, with the Aspromonte massif being formed of overlapping terraces of gneiss and mica schists.
The highest point is 1,956 m (6,417 ft) and this area is part of the Aspromonte National Park.
From the mountains flow many, often seasonal, creeks and rivers, the largest being the Amendolea and the Calopinace.
The lower hills are terraced for the cultivation of citrus fruits, olives and vines, and the higher parts are wooded, with chestnuts, beeches, holm oaks, pines, Sicilian firs and Mediterranean maquis shrubland.
The southern part of the province has a coastal plain and to the east of the mountainous area, there is a plateau that extends from the Tyrrhenian Sea to the Ionian Sea, the distance from Rosarno to Punta Stilo being about 220 kilometres (140 mi).
