The cobbled classics are four cycling classics held in March and April. Cobblestones, like mountainous terrain, are important elements in courses of cycling. Many classic cycle races in northwestern Europe contain cobbled sections. The two Monuments of this race type are the Tour of Flanders and Paris–Roubaix, with over 20 cobbled sectors.

The classic cycle races are the most prestigious one-day professional road cycling races in the international calendar. Some of these events date back to the 19th century. They are normally held at roughly the same time each year. The five most revered races are often described as the cycling monuments.
