  We study $B$ physics phenomenology in the scenario of split supersymmetry
without R-parity. By assuming the constraints of bilinear (trilinear) R-parity
violating couplings, which are introduced to solve the problem of the
atmospheric (solar) neutrino mass, we show that the decay branching ratios of
$B_{s}\to \ell^{+} \ell^{-}$ and the mixing of $B_s-\bar{B}_s$ can be large.
Explicitly, we find that $B(B_s\to\mu^+\mu^-)=O(10^{-7})$ and $\Delta
m_{B_s}=O(10^{-9}) GeV$, which should be observed at future hadron colliders.
