  In recent years precision cosmology has become an increasingly powerful probe
of particle physics. Perhaps the prime example of this is the very stringent
cosmological upper bound on the neutrino mass. However, other aspects of
neutrino physics, such as their decoupling history and possible non-standard
interactions, can also be probed using observations of cosmic structure. Here,
I review the current status of cosmological bounds on neutrino properties and
discuss the potential of future observations, for example by the recently
approved EUCLID mission, to precisely measure neutrino properties.
