Pesaro (Italian pronunciation: [ˈpeːzaro] (listen)) is a city and comune in the Italian region of Marche, capital of the Province of Pesaro e Urbino, on the Adriatic Sea. According to the 2011 census, its population was 95,011, making it the second most populous city in the Marche, after Ancona. Pesaro was dubbed the "Cycling City" (Città della Bicicletta) by the Italian environmentalist association Legambiente in recognition of its extensive network of bicycle paths and promotion of cycling. It is also known as "City of Music", for it is the birthplace of the composer Gioacchino Rossini. In 2015 the Italian Government applied for Pesaro to be declared a "Creative City" in UNESCO's World Heritage Sites. In 2017 Pesaro received the European City of Sport award together with Aosta, Cagliari and Vicenza.

Local industries include fishing, furniture making and tourism.

In 2020 it absorbed the former comune of Monteciccardo, now a frazione of Pesaro.
