Acestrorhynchus maculipinna is a species of fish in the family Acestrorhynchidae.

[2] It was described by Naércio Aquino de Menezes and Jacques Géry in 1983.

It reaches a maximum standard length of 7.9 cm (3.1 in).

[2] A. maculipinna is currently ranked as Data Deficient by the IUCN redlist, owing to postulation that the species is not at great risk of being threatened, due to a lack of fishing in large areas of its region, and the apparent robust health of its environment.
