  The Early Data Release from the Sloan Digital Sky survey provides one of the
largest multicolor photometric catalogs currently available to the astronomical
community. In this paper we present the first application of photometric
redshifts to the $\sim 6$ million extended sources within these data (with 1.8
million sources having $r' < 21$). Utilizing a range of photometric redshift
techniques, from empirical to template and hybrid techniques, we investigate
the statistical and systematic uncertainties present within the redshift
estimates for the EDR data. For $r'<21$ we find that the redshift estimates
provide realistic redshift histograms with an rms uncertainty in the
photometric redshift relation of 0.035 at $r'<18$ and rising to 0.1 at $r'<21$.
We conclude by describing how these photometric redshifts and derived
quantities, such as spectral type, restframe colors and absolute magnitudes,
are stored within the SDSS database. We provide sample queries for searching on
photometric redshifts and list the current caveats and issues that should be
understood before using these photometric redshifts in statistical analyses of
the SDSS galaxies.
