Abstract : A search for excited leptons, $\rm e^*,~\mu^*, ~\tau^*, ~\nu_e^*, ~\nu_{\mu}^*$ and $\nu_{\tau}^*$, was performed with the L3 detector at LEP using data collected at a centre--of--mass energy of 189 GeV, corresponding to an integrated luminosity of $\rm 176~pb^{-1}$. No evidence of their production is observed. From the searches for pair produced excited leptons, lower mass limits are set close to the kinematic limit. From the searches for singly produced excited leptons, upper limits on their couplings are derived in the mass range up to $189$ GeV.
