Dudváh ( Hungarian: Dudvág ) is a lowland river in western Slovakia. It is 97 km long, with a basin of 1,507 km², and with a flow of 1.3 m³/s near the village of Siladice. Its source is located in the Čachtice Little Carpathians, and it mostly runs in parallel to the Váh river. Near the town Čierna Voda, the Dudváh flows into the old branch of the Čierna voda river, which in turn flows into the Little Danube river. Near Siladice the river splits into two branches, one of which flows directly into the Váh after a few km. The other branch is also called Dolný Dudváh ("lower Dudváh").
