We investigate the LHC discovery potential of R-parity violating supersymmetric models with a right-handed selectron or smuon as the lightest supersymmetric particle. These particles arise naturally in R-parity violating minimal supergravity models. We classify the hadron collider signatures and perform for the first time within these models a detailed signal over background analysis. We develop an inclusive three-lepton search and give prospects for a discovery at a center-of-mass energy of root s = 7 TeV as well as root s = 14 TeV. There are extensive parameter regions which the LHC can already test with root s = 7 TeV and an integrated luminosity of 1 fb(-1). We also propose a method for the mass reconstruction of the supersymmetric particles within our models at root s = 14 TeV.
