The Born cross sections for the process $e^+e^- \to \eta^\prime\pi^{+}\pi^{-}$ at different center-of-mass energies between $2.00$ and $3.08$GeV are reported with improved precision from an analysis of data samplescollected with the BESIII detector operating at the BEPCII storage ring. Anobvious structure is observed in the Born cross section line shape. Fit as aBreit-Wigner resonance, it has a statistical significance of $6.3\sigma$ and amass and width of $M=(2111\pm43\pm25)$~MeV/$c^2$ and$\Gamma=(135\pm34\pm30)$~MeV, where the uncertainties are statistical andsystematic, respectively. These measured resonance parameters agree with themeasurements of BABAR in $e^+e^- \to \eta^\prime \pi^{+}\pi^{-}$ and BESIII in$e^+e^- \to \omega\pi^0$ within two standard deviations.
