Recent high-energy observations of the Galactic Center (GC) by EGRET find a significant gamma -ray excess over the diffuse background. Because of the large ~ 0.2(deg) error circle (for the emission over 1 GeV), this excess has yet to be positively identified with a particular source. However, the shape of the spectrum in combination with the power narrow the possibilities down considerably. I will discuss some models for the EGRET gamma -rays from the GC. Identifying the source is especially important in light of AGASA's detection of a 4% anisotropy in the cosmic ray flux in the direction of the GC. If one model can account for both the gamma -ray flux and the cosmic ray anisotropy, it would be the first sure confirmation of our ideas about how cosmic rays are accelerated and go on to produce high-energy emission via interactions with the ambient medium and magnetic field.
