The Adda (Latin: Abdua, or Addua; Lombard: Ada or, again, Adda in local dialects where the double consonants are marked) is a river in North Italy, a tributary of the Po. It rises in the Alps near the border with Switzerland and flows through Lake Como. The Adda joins the Po a few kilometres upstream of Cremona. It is 313 kilometres (194 mi) long. The highest point of the drainage basin is the summit of la Spedla (a subpeak of Piz Bernina), at 4,020 metres (13,190 ft).

Towns along the river Adda include Bormio, Tirano, Sondrio, Bellagio and Lecco (both on Lake Como), Brivio and Lodi. One tributary, the Poschiavino, arises in Switzerland and runs through the town of Poschiavo.
