'''Massively Parallel Quantum Chemistry''' ('''MPQC''') is an [[Ab initio quantum chemistry methods|ab initio]] [[computational chemistry]] [[software]] program.<ref name="PirhadiSunseri2016"/> Three features distinguish it from other quantum chemistry programs such as [[Gaussian (software)|Gaussian]] and [[GAMESS]]: it is [[open-source software|open-source]], has an [[object-oriented]] design, and is created from the beginning as a [[Parallel computing|parallel processing]] program.<ref>{{cite book | last1 = Janssen| first1 = Curtis L.| last2 = Nielsen| first2 = Ida M.

MPQC provides implementations for a number of important methods for calculating electronic structure, including [[Hartree&ndash;Fock]], [[Møller&ndash;Plesset perturbation theory]] (including its explicitly correlated linear R12 versions), and [[density functional theory]].
