Future Colliders

The LHC is expected to run with energies of at least 13 TeV for the next 20 years. While this will provide years of interesting proton-proton data, the field is exploring a number of other collider facilities and technologies. These include lepton colliders, Higgs factories, and very high energy hadron colliders. I will quickly review some of the main efforts, paying most attention to how they fit into the experimental and physics landscape.
