Double parton scattering is the process in which one has two hard scatterings in an individual proton-proton collision. It can compete in rate with single scattering in certain kinematic regions and/or for certain processes, reveals new information on proton structure, and becomes more important as collider energy grows. I review recent progress in the theoretical description of double parton scattering. This includes progress towards numerical predictions using a recently-developed full QCD framework, as well as calculation of higher order corrections in this framework.
