N2 - A search for the rare radiative leptonic decay Ds+→γe+νe is performed for the first time using electron-positron collision data corresponding to an integrated luminosity of 3.19 fb-1, collected with the BESIII detector at a center-of-mass energy of 4.178 GeV. No evidence for the Ds+→γe+νe decay is seen, and an upper limit of B(Ds+→γe+νe)<1.3×10-4 is set on the partial branching fraction at a 90% confidence level for radiative photon energies Eγ∗>0.01 GeV.
