  The latest results from the LHCb collaboration for the search for $CP$
violation in $b$-baryon decays are reported here. The first article presented
is the search conducted in the $\Lambda_b^0 \rightarrow p \pi^- \pi^+ \pi^- $
decay, and the subsequent observation of $P$ violation. The following paper
describes the search and the first observation of the $\Lambda_b^0 \rightarrow
D^0 p K^-$ decay, with $D^0 \rightarrow K \pi$, Cabibbo-favoured and doubly
suppressed mode. This proceeding concludes with the first amplitude analysis
performed in $\Xi_b^- \rightarrow p K^- K^-$, whose model allows for
\textit{CP} violation.
