We report a search for a magnetic monopole component of the cosmic-ray flux in a 95-day exposure of the NOvA experiment's Far Detector, a 14 kt segmented liquid scintillator detector designed primarily to observe GeV-scale electron neutrinos. No events consistent with monopoles were observed, setting an upper limit on the flux of 2×10⁻¹⁴ cm⁻² s⁻¹ sr⁻¹ at 90% C.L. for monopole speed 6×10⁻⁴ < β < 5×10⁻³ and mass greater than 5×10⁸ GeV. Because of NOvA's small overburden of 3 meters-water equivalent, this constraint covers a previously unexplored low-mass region.
