Helen Irene Battle (August 31, 1903 – June 17, 1994) was a pioneering Canadian ichthyologist and marine biologist.

[5] Even after her retirement in 1967, Battle found innovative ways to teach and was one of the first instructors to use television, taping a series of lectures for the Natural Science Centre.

Her research included examining the impact of pollutants on marine life and drinking water through the analysis of fertilized fish eggs.

[1] She also pioneered the use of fish eggs to study the effects of carcinogenic substances on cell development.

[9][10] She was an honorary member of the National Association of Biology Teachers, and in 1991, the Canadian Society of Zoologists established the Helen I.
