The Mountains classification in the Giro d'Italia is a secondary classification. In this classification, points are awarded to the leading riders over designated climbs. Most climbs are sorted into one of three scales based on difficulty and its position on that day's stage. Bonuses are given to mountain top finishes and to the first riders over the Cima Coppi, traditionally adjudged as the highest point of the entire Giro. The Cima Coppi was established in 1965 to honour the Italian cycling champion Fausto Coppi.
The classification was first calculated in 1933; from 1974 to 2011, the leader of the mountains classification in the Giro d'Italia wore the maglia verde (from Italian: "green jersey"): in 2012, as part of a sponsorship deal, the jersey colour was changed to blue (maglia azzurra).
