The giant gourami (Osphronemus goramy) is a species of large gourami native to freshwater habitats in Southeast Asia. It has also been introduced elsewhere.  It can be found in the aquarium trade, as well. The species has been used for weed control on highly invasive aquatic plants like Salvinia molesta, as the giant gourami can be a voracious herbivore.

It is capable of breathing moist air, so can survive out of water for long periods. It is much larger than most gouramis (only the other Osphronemus species reach a similar size), growing to a maximum standard length of 70 cm (28 in), though most are only around 45 cm (18 in).
