The Whakatāne Astronomical Society is a voluntary, non-profit society for people interested in amateur astronomy in the Whakatāne District of New Zealand. The society was founded in September 1960, and maintains a small observatory in Whakatāne, which has been operating continuously since 1964. The society is affiliated with the Royal Astronomical Society of New Zealand.

The Society's main fund raising activity is the running of observing nights on Tuesday and Friday evenings, where members of the public pay a small fee to view the sky using one or more of the society's telescopes at the observatory, under the guidance of a society member. Similar evenings can also be run for larger/school groups, with prior arrangement.
