The Marecchia (pronounced [maˈrekkja]) is a river in eastern Italy, flowing from near Monte dei Frati in the province of Arezzo, Tuscany, to the Adriatic Sea in Rimini, Emilia-Romagna. Along its course, the river passes next to or near the settlements of Novafeltria, Verucchio, and Santarcangelo di Romagna. It passes near the Republic of San Marino. Among its tributaries are the San Marino river and the Ausa.

The river's valley, known as the Valmarecchia, is on the border of the historic regions of Romagna and Montefeltro. On 15 August 2009, the comuni of the upper valley transferred from the province of Pesaro and Urbino, in the Marche region, to the province of Rimini in Emilia-Romagna.
