We predict a new source of jet structure in e/sup +/e/sup -/ colliding-beam experiments arising from photon-photon collisions. These jets are produced with a sizable fraction of the total observable hadronic rate and have unmistakable signatures. Observations of these jets would provide important tests of the contributions of three classes of hard-scattering mechanisms: quark exchange in ..gamma gamma.. ..-->.. qq-bar, gluon exchange in qq and qq-bar scattering, and constituent-interchange processes with a characteristic p/sub perpendicular//sup -6/ behavior.
