The Ipeľ (Slovak; pronounced [ˈipeʎ]) or Ipoly (Hungarian) (German: Eipel, archaic Slovak: Jupoľ, Latin: Bolia) is a 232-kilometre (144 mi) long river in Slovakia and Hungary, a tributary of the Danube River. Its source is in central Slovakia in the Slovak Ore Mountains. It flows south to the Hungarian border and the Slovakia-Hungary border, and then southwest, west, and again south along the border until it flows into the Danube near Szob.

The Ipeľ flows through or creates the border of the Banská Bystrica and Nitra regions in Slovakia, and Nógrád and Pest counties in Hungary.
