Do neutrinos have mass? The answer to this question could alter our current understanding of the cosmos as well as how these elusive particles fit into the Standard Model. Evidence for neutrino oscillations has been seen by experiments studying several different sources of neutrinos - solar, atmospheric and accelerator-based. The results from solar and atmospheric neutrino experiments as well as the accelerator neutrino experiment, LSND, will be discussed. Experiments designed to resolve the outstanding questions about neutrino mass and mixing, in particular, the MiniBooNE experiment at Fermilab, will be described.
