  We present the impact of two-loop corrections on the mass of the lightest
Higgs boson in the Minimal R-symmetric Supersymmetric Standard Model (MRSSM).
These shift the Higgs boson mass up by typically 5 GeV or more. The dominant
corrections arise from strong interactions, from the gluon and its N=2
superpartners, the sgluon and Dirac gluino, and these corrections further
increase with large Dirac gluino mass. The two-loop contributions governed
purely by Yukawa couplings and the MRSSM $\lambda,\Lambda$ parameters are
smaller. We also update an earlier analysis [Diessner:2014ksa], which showed
that the MRSSM can accommodate the measured Higgs and W boson masses. Including
the two-loop corrections increases the parameter space where the theory
prediction agrees with the measurement.
