The standard model of cosmology makes definite and robust predictions about the existence and properties of the cosmic neutrino background.  These neutrinos carry a wealth of information about both cosmology and particle physics, but they are notoriously difficult to observe.  Rapid advancement in measurements of the cosmic microwave background, however, have allowed us to indirectly constrain some properties of the cosmic neutrino background.  I will discuss the current status and future prospects for observation of cosmic neutrinos.
