  We report on forward-rapidity charmonium production in pp collisions at a
center of mass energy $\sqrt{s} = 13$ TeV, as measured by ALICE at the LHC.
Differential cross sections for both J/{\psi} and {\psi}(2S) are presented as a
function of the charmonium transverse momentum and rapidity. Results are
compared to similar measurements performed by LHCb, to lower energy
measurements and to state of the art model calculations.
