The Polcevera (in Ligurian Pûçéivia or Ponçéivia) is a 19-kilometre (12 mi) river in Liguria (Italy).

Between Pontedecimo and the Ligurian Sea, the Polcevera is 11 kilometres (6.8 mi) long, but its total length including the Torrente Verde is 19 kilometres (12 mi).

From Pontedecimo the Polcevera heads south, and at Bolzaneto it receives the waters of the Torrente Secca, another important left-hand tributary.

After being crossed by the Ponte Morandi, a motorway bridge that partially collapsed in August 2018,[3] it ends its course in the Ligurian Sea between Sampierdarena and Cornigliano, two quartieri of Genoa.

The 140-square-kilometre (54 sq mi) drainage basin of the Polcevera is totally included in the Province of Genova.
