Results from Super-Kamiokande on atmospheric neutrinos and solar neutrinos
are presented. The atmospheric neutrino data exhibited a zenith angle depen
dent deficit of muon neutrinos. Experimental biases and uncertainties in th
e prediction were unable to explain the data. However, the data were in goo
d agreement with two flavor nu(mu) <----> nu(tau), oscillations. The solar
neutrino data showed a deficit of the neutrinos. The day-night effect and t
he energy spectrum of recoil electrons were studied.
