An approximate expression for the damping coefficient of an electron plasma wave with a finite amplitude is obtained. It is given in the form, γ_<NL>(τ)=γ_L[1-(E^^-_<0^2>)/(64)(2/3τ^3-τ^2+τ-1/2+1/2e^<-2τ>)] where γ_L and γ_<NL> stand for 'the linear and the non-linear Landau damping coefficients'. Here τ and E^^-(τ) are adequately stretched time and electric field, and E^^-_0=E^^-(0). The above expression is valid for τ<<ω_<B^<-1>> where ω_B is the bouncing frequency of electrons trapped in a potential trough of the wave.
