The Lugano Prealps (Prealpi Luganesi or Prealpi Lombarde Occidentali in Italian) are a mountain range in the western part of the Alps. They are located in Canton Ticino (southern Switzerland) and Lombardy (northern Italy).

Administratively the Italian part of the range belongs to the provinces of Como and Varese, while the Swiss one is divided between the districts of Bellinzona, Locarno, Lugano and Mendrisio.

The western slopes of the mountains are drained by the Ticino, the eastern ones by Adda and the southern-central part of them by Lambro, Olona and other minor rivers and streams, all of them directly or indirectly tributaries of the Po.

According to SOIUSA (International Standardized Mountain Subdivision of the Alps) the mountain range is an Alpine section, classified in the following way:^[2]

• main part = Western Alps
• major sector = North Western Alps
• section = Lugano Prealps
• code = I/B-11

Lugano Prealps' borders are (clockwise):

• Lago Maggiore (west),
• Ticino from Locarno to Bellinzona, San Jorio Pass (2.010 m, which connects them with the Lepontine Alps) and San Jorio valley till to Gravedona (north);
• Como lake (east);
• Po Plain (south).

The Lugano Prealps are divided into two subsections:^[2]

• Como Prealps - SOIUSA code:I/B-11.I
• Varese Prealps - SOIUSA code:I/B-11.II,

which are separated by the Monte Ceneri Pass.

These subsections are further divided in supergroups:

• Como Prealps:
  • supergroup catena Gino-Camoghè-Fiorina - SOIUSA code:I/B-11.I-A
  • supergroup catena Tremezzo-Generoso-Gordona - SOIUSA code:I/B-11.I-B
  • supergroup catena del Triangolo Lariano - SOIUSA code:I/B-11.I-B
• Varese Prealps:
  • supergroup catena Tamaro-Gambarogno-Lema - SOIUSA code:I/B-11.II-A,
  • supergroup catena Piambello-Campo dei Fiori-Nudo - SOIUSA code:I/B-11.II-B.
