The Galga is a right tributary of the river Zagyva in the Cserhát mountains and the Great Hungarian Plain, Hungary.{{cite book |last1=Görgey |first1=Artúr |title=My Life and Acts in Hungary in the 1848 and 1849 |date=1852 |publisher=David Bogue |url=https://books.google.com/books?id=617RAAAAMAAJ&dq=%22Galga%22+-wikipedia+Zagyva&pg=PA329 |language=en}} It originates at Becske, Nógrád County, at the Hill Szandai. The river flows into the Zagyva at Jászfényszaru.

Because of the major disasters caused by the river overflowing in the 1970s, it became regulated by the Aszód-based GAVIT, which is responsible for the Galga and all of the streams flowing into the river.
