In theoretical physics, Seiberg-Witten gauge theory is a set of calculations that determine the low-energy physics — namely the moduli space and the masses of electrically and magnetically charged supersymmetric particles as a function of the moduli space.

This is possible and nontrivial in gauge theory with N = 2 extended supersymmetry by combining the fact that various parameters of the Lagrangian are holomorphic functions (a consequence of supersymmetry) and the known behavior of the theory in the classical limit.

The moduli space in the full quantum theory has a slightly different structure from that in the classical theory.
