The Marbella municipality occupies a strip of land that extends along forty-four kilometres (27 miles) of coastline of the Penibético region, sheltered by the slopes of the coastal mountain range, which includes the Bermeja, Palmitera, Royal, White and Alpujata sub-ranges. Due to the proximity of the mountains to the coast, the city has a large gap between its north and south sides, thus providing views of the sea and mountain vistas from almost every part of the city. The coastline is heavily urbanised; most of the land not built up with golf courses has been developed with small residential areas. Map of Marbella. Marbella is bordered on the north by the municipalities of Istán and Ojén, on the northwest by Benahavís, on the west by Estepona and on the northeast by Mijas. The Mediterranean Sea lies to the south.

There are five geomorphological units: the Sierra Blanca, the Sierra Blanca piedmont (foothills), the lower hill country, the plains and the coastal dunes. The Sierra Blanca is most centrally located in the province, looming over the old village. This mountain range has three peaks: La Concha, located further west at 1,215 m above sea level, Juanar Cross, located eastward (within the municipality of Ojen) at 1,178 m above sea level, and the highest, Mount Lastonar, located between the two at 1,270 metres. Marbella's topography is characterised by extensive coastal plains formed from eroded mountains. After the plain lies an area of higher elevations of between 100 and 400 m, occupied by low hills, behind which rise the foothills and steeper slopes of the mountains. The coast is generally low and sandy beaches that are more extensive further east, between the fishing port and the Cabopino. Despite the intense urbanisation of the coast, it still retains a natural area of dunes at the eastern end of town, the Artola Dunes (Dunas de Artola).
