At the end of the EGRET mission, only 6 Galactic sources in the 3rd EGRET catalog  had firm identifications: 5 young pulsars and a solar flare. Another dozen or so had plausible counterparts. Now, at the dawn of the GLAST era, around 30 sources detected at other wavelengths have been identified as probable or plausible counterparts. These include nearly all of the sources with significant emission above 1 GeV, which will be the sources GLAST will best be able to study. I review the current status of our knowledge of these sources based on radio, infrared, and X-ray data. These Galactic sources are destined to be the first sources firmly identified by GLAST.
