  We investigate the connection between R-parity violation (RPV) in
supersymmetric models and Baryogenesis. First we discuss in detail the
assumptions of a theorem by Nanopoulos and Weinberg on the CP asymmetry
generated from the decay of massive particles. In light of this statement, we
analyse some interesting models of Baryogenesis through RPV. We then explore,
in the context of RPV SUSY, the possibility to generate the baryon asymmetry
through the out-of-equilibrium decay of a metastable Weakly Interacting Massive
Particle (WIMP), as proposed in \cite{Cui:2012jh}. This setting is also
motivated by the observed coincidence between the abundances of dark and
baryonic matter. In this framework, we propose two models of out-of-equilibrium
decay of a would-be cold relic, and compute the associated CP asymmetry. With a
TeV-scale parent, the observed baryon abundance can be reproduced in these
models when the stop is in the multi-TeV region. Furthermore, annihilation of
the metastable particle into SM states must be characterised by a very weak
coupling, $g\sim 10^{-2}$ and by a heavy mediator $m_{med}\sim 10$ TeV. These
models can also accommodate stop masses far from the TeV scale, at the expense
of weakening the explanation of the $\Omega_{B}-\Omega_{DM}$ coincidence.
