GAMESS (US) is a computational chemistry software program that stands for General Atomic and Molecular Electronic Structure System.〔 (This is one of the most cited chemistry articles ) 〕〔As of May 2013, the GAMESS code lists its contributors as: Michael W.

GAMESS (US) is maintained by the members of the (Gordon research group ) at Iowa State University. GAMESS (US) source code is available at no cost, but is not considered open source, because of license restrictions. == Capabilities == GAMESS (US) can perform a number of general computational chemistry calculations, including Hartree–Fock, density functional theory (DFT), generalized valence bond (GVB), and Multi-configurational self-consistent field (MCSCF). Correlation corrections after these SCF calculations can be estimated by configuration interaction (CI), second order Møller–Plesset perturbation theory (MP2), and coupled cluster (CC) theory. Solvent effect can be considered using quantum mechanics/molecular mechanics through discrete effective fragment potentials or continuum models (such as PCM). Relativistic corrections can be calculated, including third order Douglas-Kroll scalar terms. While the program does not directly perform molecular mechanics, it can do mixed quantum mechanics/molecular mechanics calculations through effective fragment potentials or through an interface with the TINKER code. The fragment molecular orbital method can be used to treat large systems, by dividing them into fragments. It can also be interfaced with the valence bond VB2000 and XMVB programs and the Natural Bond Orbital (NBO) population analysis program. The input files use a keyword based scheme.
