The Trittico di Autunno (Italian for "Autumn Triptych") is an unofficial trio of one-day road cycling classics held in October in northern Italy. It is not an official competition like its counterpart, the Trittico Lombardo. The three races that compose the Trittico di Autunno are:
- Milano–Torino
- Gran Piemonte (formerly Giro del Piemonte)
- Giro di Lombardia
These three races are typically held within a four-day timeframe in the Lombardy and Piedmont regions, between mid-September and mid-October. All three are organized by RCS Sport.
Historically, the placement of these races in the calendar has varied. Before 1987, Milano–Torino was organized in the spring, which was also the case in 2005, 2006, and 2007. The Giro del Piemonte had a variable calendar position until 1970, and only since 1971 has it been consistently held between September and October. The Giro di Lombardia has traditionally been a late-season race, held in October or November.
Only four riders have won all three races in the Trittico di Autunno over the course of their careers: Giovanni Gerbi, Costante Girardengo, Gaetano Belloni, and Roger De Vlaeminck. Costante Girardengo is the only rider to have won all three in the same year (1919), though at that time Milano–Torino was held in April and the Giro del Piemonte in May.
