Bryconops marabaixo is a species of freshwater ray-finned fish belonging to the family Iguanodectidae. This species is found in the lower Amazon basin, native to the Rio Jari. It is small and silvery, with a dark-gray back, and its fins are mostly clear, though the caudal fin has a dark stripe on the lower margin of the dorsal lobe, and a spot of red pigment just above that. Like many other members of Bryconops, it has a humeral spot, which is a mark near each pectoral fin.

Bryconops marabaixo was officially named in 2020, though it was the secondary focus of the nominal article. The study that described it had the primary purpose of solidifying a proper description for congener Bryconops cyrtogaster, to which it has some superficial resemblance.
