Abstract: We present results from the NIRVANDELS survey on the gas-phase metallicity (Z<SUB>g</SUB>, tracing O/H) and stellar metallicity (Z<SUB>⋆</SUB>, tracing Fe/H) of 33 star-forming galaxies at redshifts 2.95 < z < 3.80. Based on a combined analysis of deep optical and near-IR spectra, tracing the rest-frame far-ultraviolet (FUV; 1200-2000 Å) and rest-frame optical (3400-5500 Å), respectively, we present the first simultaneous determination of the stellar and gas-phase mass-metallicity relationships (MZRs) at z ≃ 3.4. In both cases, we find that metallicity increases with increasing stellar mass (M<SUB>⋆</SUB>) and that the power-law slope at M<SUB>⋆</SUB> ≲ 10<SUP>10</SUP>M<SUB>⊙</SUB> of both MZRs scales as $Z \propto M_{\star }^{0.3}$. Comparing the stellar and gas-phase MZRs, we present direct evidence for super-solar O/Fe ratios (i.e. α-enhancement) at z > 3, finding (O/Fe) = 2.54 ± 0.38 × (O/Fe)<SUB>⊙</SUB>, with no clear dependence on M<SUB>⋆</SUB>.
