Rubidium perchlorate, RbClO₄, is the perchlorate of rubidium. It is an oxidizing agent, as are all perchlorates.

It has two polymorphs. One, below 279 °C crystallizes in orthorhombic crystal system with lattice constants a = 0.927 nm, b = 0.581 nm, c = 0.753 nm. Over 279 °C, it has cubic structure with lattice constant a = 0.770 nm.^[1]
