We study the impact of R-parity violating Supersymmetry (RPV SUSY) on the 125GeV Higgs production and decay modes at the LHC. We assume a heavy SUSYspectrum with multi-TeV squarks and SU(2) scalar singlets as well as thedecoupling limit in the SUSY Higgs sector. In this case the lightest CP-evenHiggs is SM-like when R-parity is conserved. In contrast, we show that whenR-parity violating interactions are added to the SUSY framework, significantdeviations may occur in some production and decay channels of the 125 GeVHiggs-like state. Indeed, we assume a single-flavor (mostly third generation)Bilinear RPV (BRPV) interactions, which generate Higgs-sneutrino mixing,lepton-chargino mixing and neutrino-neutralino mixing, and find that notabledeviations of ${\cal O}(20-30\%)$ may be expected in the Higgs signal strengthobservables in some channels, e.g., in $p p \to h \to \mu^+ \mu^-, \tau^+\tau^-$. Moreover, we find that new and detectable signals associated with BRPVHiggs decays to gauginos, $h\rightarrow\nu_{\tau}\tilde{\chi}_{2}^{0}$ and$h\rightarrow\tau^{\pm}\chi_{2}^{\mp}$, may also arise in this scenario. Thesedecays yield a typical signature of $h \to \tau^\pm \ell^\mp + {{\not\!\!E_T}}$ ($\ell =e,\mu,\tau$) that can be much larger than in the SM, and mayalso be accompanied by an ${\cal O}(20-30\%)$ enhancement in the di-photonsignal $pp \to h \to \gamma \gamma$. We also examine potential interestingsignals of Trilinear R-parity violation (TRPV) interactions in the productionand decays of the Higgs-sneutrino BRPV mixed state (assuming it is the 125 GeVscalar) and show that, in this case also, large deviations up to ${\calO}(100\%)$ are expected in e.g., $p p \to h \to \mu^+ \mu^-, \tau^+ \tau^-$,which are sensitive to the BRPV$\times$TRPV coupling product.
