The Born cross sections for the process e+e → η'π+π at different center-of-mass energies between 2.00 and 3.08 GeV are reported with improved precision from an analysis of data samples collected with the BESIII detector operating at the BEPCII storage ring. An obvious structure is observed in the Born cross section line shape. Fit as a Breit-Wigner resonance, it has a statistical significance of 6.3σ and a mass and width of M = (2111 ± 43 ± 25) MeV/c2 and Γ = (135 ± 34 ± 30) MeV, where the uncertainties are statistical and systematic, respectively. These measured resonance parameters agree with the measurements of BABAR in e+e → η'π+π and BESIII in e+e → ωπ0 within two standard deviations.
