Proaulopora is a Cambrian–Ordovician fossil genus of calcareous algae.

It was originally established by the Russian paleontologist Aleksandr Grigoryevich Vologdin [ru] in 1937, for species known from the Lower Cambrian of the western Altai Mountains.

[1][2] In some older classifications of fossil algae genera, Proaulopora is placed in the family Proauloporaceae in order Proauloporales.

[3][4] In 2020, the genus was assigned to the cyanobacteria order Nostocales.

[5] Proaulopora resembles some species of the extant rivulariacean genus Dichothrix, and has also been compared with the genus Calothrix.
