Penrhos College is an independent Uniting Church single-sex primary and secondary day and boarding school for girls, located in Como, a southern suburb of Perth, Western Australia.

The school takes pride in its 17 consecutive wins in the IGSSA athletics, and almost as many in the cross country and swimming events.

The school's new name was drawn from Penrhos College, in Colwyn Bay, North Wales, which was established in 1880 by the Methodist Church, for the special education of girls.

Penrhos College is situated on a single suburban campus in an elevated position, on a former pine plantation.

The school is 8 hectares (20 acres) in size, featuring a parkland setting and modern cream brick and terracotta-tiled buildings.
