We investigate the potential of the early LHC to discover the signal of monotops, which can be decay products of some resonances in models such as R-parity violating SUSY and SU(5). We show how to constrain the parameter spaces of the models using the $Z$ boson hadronic decay branching ratio, $K^0-\bar{K^0}$ mixing and dijet experiments at the LHC, and study the sensitivities to the parameters at the LHC with $\sqrt{s}$=7 TeV and an integrated luminosity of $1 {\rm fb}^{-1}$ in detail. Our results show that the early LHC may detect this signal at a 5$\sigma$ level for some regions of the parameter space allowed by current precise data.
