There were three main individual classifications contested in the 1975 Giro d'Italia, as well as a team competition. Three of them awarded jerseys to their leaders. The general classification was the most important and was calculated by adding each rider's finishing times on each stage. The rider with the lowest cumulative time was the winner of the general classification and was considered the overall winner of the Giro. The rider leading the classification wore a pink jersey to signify the classification's leadership.
