The Giro di Lombardia, officially Il Lombardia, is a cycling race in Lombardy, Italy. It is traditionally the last of the five 'Monuments' of the season, considered to be one of the most prestigious one-day events in cycling, and one of the last events on the UCI World Tour calendar. Nicknamed the Classica delle foglie morte, it is the most important Autumn Classic in cycling. The race's most famous climb is the Madonna del Ghisallo in the race finale.

The Monuments are five classic cycle races generally considered to be the oldest, hardest, longest and most prestigious one-day events in men's road cycling, with distances between 240 and 300 km.
