We present the most comprehensive set of empirical optical strong-line metallicity calibrations to date, based on the DEep Spectra of Ionised REgions Database (DESIRED), the largest compilation of HII regions and galaxies with direct electron temperature determinations. We construct a high-quality calibration sample of 2392 spectra: 1029 extragalactic HII regions, 1296 local star-forming galaxies, and 67 high-redshift (
