I will recall briefly the role played by colliders in neutrino physics and discuss what new high luminosity colliders could do in the future.
The seminar will address in particular the Future Circular Collider project, a powerful new 100 km exploration machine to replace the LHC at the end of the presently planned program, and which will support a high luminosity e+e- collider as a Z,W,Higgs and top factory and ultimately a 100 TeV proton collider
