Abstract: We construct the quasiparton distributions of mesons for two-dimensional QCD with either scalar or spinor quarks using the $1/{N}_{c}$ expansion. We show that in the infinite momentum limit, the parton distribution function is recovered in both leading and subleading order in $1/{N}_{c}$.
