CP violation is well established in meson decays, including strange, charm and beauty mesons, but it has yet to be confirmed in baryon decays. The LHCb experiment, designed for precision studies of CP violation, has collected an unprecedented amount of beauty baryons, providing a unique opportunity to search for CP violation in charmless $Λ_b^0$ baryon decays, where significant CP violation is expected. This talk will present the latest results from the search for CP violation in $\Lambda_b^0 \to \Lambda h^+ h^{\prime -}$ and $\Lambda_b^0 \to ph^-$, $h ,h^\prime = K, \pi$ decays, using 9 $fb^(-1)$ of pp collision data collected by the LHCb experiment.
