The low-lying low-spin levels of $sup 94$Nb have been investigated; these levels were populated via the $sup 94$Zr(p,n$gamma$$)$$sup 94$Nb reaction with a separated isotope $sup 94$Zr foil target (96% $sup 94$Zr). Excitation functions of $gamma$ rays were obtained at incident proton energies from 1.688 to 3.700 MeV. $gamma$$-$$gamma$ coincidences were observed at E/subp/=3.0 MeV. The existence of additional levels at 301.5, 450.3, 666.2, and 785.0 keV has been established. Computed Hauser-Feshbach (p,n') cross sections have been fitted to experimental cross sections deduced from the $gamma$-ray data with the resulting best-fit spin-parities: 140.4-keV level, 2$sup -$; 301.5, 2$sup -$; 334.2, 3$sup +$; 396.3, 4$sup -$; and 450.3, 3$sup +$.
