Understanding electron neutrino interactions is crucial for measurements of neutrino oscillations and searches for new physics in neutrino experiments. We present the first measurement of the flux-averaged ν_{e}+ν[over ¯]_{e} charged-current single charged-pion production cross section on argon using the MicroBooNE detector and data from the NuMI neutrino beam. The total cross section is measured to be [0.93±0.13(stat)±0.27(syst)]×10^{-39} cm^{2}/nucleon at a mean ν_{e}+ν[over ¯]_{e} energy of 730 MeV. Differential cross sections are also reported in electron energy, electron and pion angles, and electron-pion opening angle.
