  We present the first determination of the near-infrared K-band luminosity
function of field galaxies from a wide field K-selected redshift survey. The
best fit Schechter function parameters are $M^* = -23.12 +5log(h)$, $\alpha =
-0.91$, and $\phi^* = 1.66 \times 10^{-2} h^3 ~ Mpc^{-3}$. We estimate that
systematics are no more than 0.1 mag in $M^*$ and 0.1 in $\alpha$, which is
comparable to the statistical errors on this measurement.
