he objective of this research was to investigate the development of a reliable fingerprint from elemental and isotopic signatures of Argentinean honey to assess its geographical provenance. Honey, soil, and water from three regions (Coŕ doba, Buenos Aires, and Entre Rıó s) were collected. The multielemental composition was determined by ICP-MS. δ13C was measured by isotopic ratio mass spectrometry, whereas the 87Sr/86Sr ratio was determined using thermal ionization mass spectrometry. The data were analyzed by chemometrics looking for the association between the elements, stable isotopes, and honey samples from the three studied areas. Honey samples were differentiated by classification trees and discriminant analysis using a combination of eight key variables (Rb, K/Rb, B, U, 87Sr/86Sr, Na, La, and Zn) presenting differences among the studiedregions. The application of canonical correlation analysis and generalized procrustes analysis showed 91.5% consensus bet
