Models with quark and lepton compositeness predict the existence of colored partners of the Standard Model leptons. In this paper we study the LHC phenomenology of a charged colored lepton partner, namely the color octet electron, $e_8$. We explore various production mechanisms of the $e_8$'s at the LHC. Assuming 100% branching ratio for the decay, $e_8\to eg$, we estimate the LHC discovery potential for the $e_8$'s. Our analysis shows that the LHC with 14 TeV center of mass energy and 100 fb$^{-1}$ (300 fb$^{-1}$) of integrated luminosity can probe $e_8$ mass up to 3 TeV (3.4 TeV) for the compositeness scale of 5 TeV.
