Radio and X-ray observations of stellar flares provide the most direct
probes of energy release, particle acceleration, and energy transport
on stars other than the Sun. In this review, the observational basis
for our understanding of the flare phenomenon on other stars is briefl
y described and outstanding interpretive and theoretical issues are di
scussed. I shall confine my attention to objects which are ''solar-lik
e'', to the extent that they possess deep convective envelopes and dis
play activity which is presumed to be magnetic in origin. These includ
e pre-main sequence objects, classical flare stars, and close binaries
. Future directions are briefly discussed.
