Ian Stafford Ross Munro (1919–1994) was an Australian ichthyologist and marine biologist.
Munro grew up in Brisbane and received degrees from the University of Queensland in the early 1940s, studying marine biology, while also conducted service in the Australian Reserve Military Forces (as part of WW2)[1].
In 1943 he started work as an assistant research officer with the CSIR Division of Fisheries at Cronulla, New South Wales[1], which became the CSIRO after 1956[2].
Earlier, Munro had worked to document the poorly known fish fauna off northern Australian and New Guinea, and from 1948-1950 he participated in fisheries surveys in the region to document the fish fauna[1].
One of Munro's more important legacies was starting the Australian National Fish Collection (ANFC) at CSIRO, known as the "I. S. R. Munro Ichthyological Collection" in his honor until its recent name change to the ANFC[1].
