Abstract	Measurements are presented for the measurements of the differential and double differential Drell-Yan cross section using an integrated luminosity of $4.5$~fb$^{-1}$ (dimuon) and $4.8$~fb$^{-1}$ (dielectron) of proton-proton collision data recorded with the CMS detector at the LHC at $\sqrt{s} = 7$~TeV. The cross sections $d\sigma/dM$ are measured in the mass range $15$~GeV to $1500$~GeV for the dimuon, dielectron, and combined channels. Results are also presented on the measurement of the double-differential cross section $d^2\sigma/dMdY$ in the dimuon channel. The double-differential cross section measurement is performed over the mass range $20$~GeV to $1500$~GeV and absolute dimuon rapidity from $0$ to $2.4$. The differential cross section measurements are normalized to the $Z$-peak region ($60 - 120$~GeV) to achieve better accuracy. The measurements are compared to the predictions of perturbative QCD calculations at next-to-leading and next-to-next-to-leading order using various sets of parton distribution functions.
