Abstract. Results from Super-Kamiokande-I's entire 1496 live days of solar neutrino data are presented, including the absolute flux, energy spectrum, zenith angle (day/night) and seasonal variation. The possibility of MSW and vacuum oscillations is discussed in light of these results. Results from the first 1289 days of Super-K-I's atmospheric neutrino analysis are also presented, including the evidence for $\nu_\mu \rightarrow \nu_\tau$ oscillations, against $\nu_\mu \rightarrow \nu_{\rm sterile}$ oscillations, and the current limits on proton decay. Finally, results based on $5.6 \times 10^{19}$ protons on target are given for the K2K long-baseline neutrino oscillation experiment.

Keywords. Neutrino; solar; atmospheric; oscillation; long-baseline.
