GSO projection refers to a type of projection used in the field of mathematics, specifically in geometry and topology, related to the study of high-dimensional spaces. The term "GSO" typically comes from the initials of the authors or researchers associated with the method or can stand for concepts in relation to geometric structures.

The Gliozzi–Scherk–Olive projection selects consistent worldsheet fermion-number and chirality sectors in an RNS string theory. In suitable supersymmetric choices it removes the tachyonic Neveu–Schwarz sector ground state and keeps a chosen Ramond sector chirality. Together with the consistent sector combinations it produces spacetime fermions and, for theories such as Type II superstring theory, a tachyon-free spectrum. The mere presence of classical worldsheet supersymmetry does not specify this projection or guarantee tachyon removal.
