The Helpe Mineure (French pronunciation: [ɛlp minœʁ], literally Helpe Minor or Little Helpe) is a river in France, which flows through the regions of Hauts-de-France. It arises in the municipality of Ohain at the confluence of two source streams. The river drains and flows in a generally north-westerly direction for about 50 kilometres (31 mi) before it flows into its confluence as a southern tributary of the Sambre north-west of Maroilles.
