Pandrosion of Alexandria (Ancient Greek: Πανδροσίων) was a mathematician in fourth-century-AD Alexandria, discussed in the Mathematical Collection of Pappus of Alexandria and known for having possibly developed an approximate method for doubling the cube. Although there is disagreement on the subject, Pandrosion is believed by many current scholars to have been female. If so, she would be an earlier female contributor to mathematics than Hypatia.
