  We examine the large branching ratio for the process $B\to \eta^{\prime} K$
from the standpoint of R parity violating supersymmetry. We have given all
possible $R_p$ violating contributions to $B\to \eta^{\prime} K$ amplitudes. We
find that only two pairs of $\lambda^{\prime}$-type $R_p$ violating couplings
can solve this problem after satisfying all other experimental bounds. We also
analyze those modes where these couplings can appear, {\em e.g.}, $B^\pm \to
\pi^{\pm}K^0$, $B^{\pm,0} \to K^{*\pm,0} \eta^{(\prime)}$, $B^{\pm} \to\phi
K^{\pm}$ etc., and predict their branching ratios. Further, one of these two
pairs of couplings is found to lower the branching ratio of $B^{\pm}\to\phi
K^\pm$, thereby allowing larger $\xi\equiv{1\over N_c}$. This allows us to fit
$B^{\pm}\to \omega K^{\pm}$ and $B^{\pm}\to \omega \pi^{\pm}$, which could not
be done in the SM framework.
