The Sieve is a river in Italy. It is a tributary of the Arno, into which it flows at Pontassieve after a course of 62 km. The Sieve rises in the Tuscan-Emilian Apennines, near the Futa Pass, at 930 m of elevation.

The territory in which it flows is known in Italian as Valdisieve. In Italian language, the name "Sieve" is feminine, and is therefore referred to as La Sieve.
