  We consider CP violation due to left-right mixing in a class of Left-Right
symmetric models and show that it leads to observable effects in hyperon
decays. For S-wave, the contribution to CP violating asymmetry A of the
polarization in hyperon and anti-hyperon decays is proportional to
$\epsilon'/\epsilon$. While the tree level L-R operators contribution is
constrained to be less than $ 10^{-5}$, the gluon penguin operator contribution
can be as large as $10^{-4}$. For P-wave, the contribution is not directly
related to $\epsilon'/\epsilon$. Its contribution to A can be larger and may
reach $6\times 10^{-4}$ in $\Lambda \rightarrow p\pi^-$. This is much larger
than the value expected for A in the Standard Model.
