Proaulopora is a Cambrian–Ordovician fossil genus of calcareous algae. It has been variously thought to belong to the green algae, red algae or cyanobacteria. It was originally established by the Russian paleontologist Aleksandr Grigoryevich Vologdin in 1937, for species known from the Lower Cambrian of the western Altai Mountains.
In some older classifications of fossil algae genera, Proaulopora is placed in the family Proauloporaceae in order Proauloporales. In 2020, the genus was assigned to the cyanobacteria order Nostocales.
Proaulopora resembles some species of the extant rivulariacean genus Dichothrix, and has also been compared with the genus Calothrix.
