This study presents a comprehensive characterization of propolis collected from four Northern Iraqi regions: Erbil, Mosul, Duhok, and Sulaymaniyah. The chemical content was examined through LC\u2013MS\/MS, ICP\u2013MS, and GC\u2013MS. Extracts were also evaluated for their antioxidant, enzyme inhibitory, and antimicrobial activities. LC\u2013MS\/MS profiling revealed notable regional and solvent\u2010dependent variations in phenolic and flavonoid content, with ethanol extracts, particularly from Mosul and Sulaymaniyah, being richer in galangin, chrysin, and naringenin. GC\u2013MS analysis identified several fatty acids and phenolic esters, with Duhok propolis containing high palmitic acid. ICP\u2013MS analysis indicated variation in macroelements and trace elements, showing abundant calcium, magnesium, and iron. Ethanol extracts exhibited superior antioxidant activity in both DPPH radical scavenging and total antioxidant capacity, with Sulaymaniyah and Duhok extracts being the most active.
