River Mareza is a small river that originates in Mareza Springs, some 3 km northwest of Podgorica's neighbourhood of Tološi. The Mareza Springs are well known as a source of premium quality drinkable water that Podgorica is famous for. It also provides water for Mareza fish pond, an artificial pond created for fish breeding. From there on, Mareza generally has a form of a small canal, and empties into the Morača River just south of Podgorica.
Mareza is also a name of a settlement around the Mareza Springs. It is a favourite excursion site of Podgorica citizens, partly because it has a few degrees lower temperature than Podgorica city in the summer months. It is also a home of one of the Plantaže restaurants, famed for its traditional Montenegrin cuisine. It is somewhat exclusive residential area, one of the residents being the Mayor of Podgorica, Miomir Mugoša.
