A search for boosted dark matter using 161.9 kiloton-years of<br />
Super-Kamiokande IV data is presented. We search for an excess of elastically<br />
scattered electrons above the atmospheric neutrino background, with a visible<br />
energy between 100 MeV and 1 TeV, pointing back to the Galactic Center or the<br />
Sun. No such excess is observed. Limits on boosted dark matter event rates in<br />
multiple angular cones around the Galactic Center and Sun are calculated.<br />
Limits are also calculated for a baseline model of boosted dark matter produced<br />
from cold dark matter annihilation or decay.
