The Sesia (Latin Sesites or Sessites) is a river in north-western Italy, tributary to the Po.

Its sources are the glaciers of Monte Rosa at the border with Switzerland. It flows through the Alpine valley Valsesia and the towns Varallo Sesia, Quarona, Borgosesia and Vercelli. The Sesia flows into the Po River near Casale Monferrato.

It is a popular river for kayaking and hosted the European championship in 2001 and the world championship in 2002.
