  We study the chiral properties of quenched domain wall fermions with several
gauge actions. We demonstrate that the residual chiral symmetry breaking, which
is present for a finite number of lattice sites in the fifth dimension ($L_s$),
can be substantially suppressed using improved gauge actions. In particular the
Symanzik action, the Iwasaki action, and a renormalization group improved gauge
action, called doubly blocked Wilson (DBW2), are studied and compared to the
Wilson action. All improved gauge actions studied show a reduction in the
additive residual quark mass, $\mres$. Remarkably, in the DBW2 case $\mres$ is
roughly two orders of magnitude smaller than the Wilson gauge action at
$a^{-1}=2$ GeV and $L_s=16$. Significant reduction in $\mres$ is also realized
at stronger gauge coupling corresponding to $a^{-1}=1.3$ GeV. As our numerical
investigation indicates, this reduction is achieved by reducing the number of
topological lattice dislocations present in the gauge field configurations. We
also present detailed results for the quenched light hadron spectrum and the
pion decay constant using the DBW2 gauge action.
