Euplectella sanctipauli is a species of glass sponge in the family Euplectellidae.

[1] It is known from type specimens found off the coast of Brazil.

The generic name, Euplectella, is derived from the Latin plecto, meaning "to weave", and the prefix eu-, in reference to the "complexity of the interweaving of its component threads".

[2] The specific epithet, sanctipauli, is derived from the São Paulo Ridge in the southwest Atlantic Ocean, the type locality of the species.
