The Orlovka (Russian: Орловка), also known as Mamyn (Russian: Мамын), is a river in Mazanovsky District, Amur Oblast, Russia. It is the 4th longest tributary of the Selemdzha after the Byssa, with a length of 208 kilometres (129 mi) and the second in drainage basin area, with 11,300 square kilometres (4,400 sq mi).

The river basin includes the Garinskoye iron ore deposit, one of the largest in the Russian Far East, as well as gold prospecting areas. The only settlement in the river basin is Oktyabrsky, located by river Gar, the main tributary. In the past there had been other settlements by the river, such as the Slava collective farm on the left bank near the mouth, but they were abandoned.
