Antimicrobial resistance (AMR) is a recurring global problem, which constantly demands new antimicrobial compounds to challenge the resistance. It is well known that essential oils (EOs) have been known for biological activities including antimicrobial properties. In this study, EOs from seven aromatic plants of Asir region of southwestern Saudi Arabia were tested for their antimicrobial efficacy against four drug resistant pathogenic bacterial isolates ( Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli,  and  Streptococcus typhimurium)  and one fungal isolate ( Candida albicans) . Chemical compositions of EOs were determined by gas chromatography-mass spectrometry (GC-MS). The results revealed that EOs from  Mentha cervina ,  Ocimum basilicum,  and  Origanum vulgare  proved most active against all isolates with inhibitory zone range between 17 and 45 mm. The lowest minimum inhibitory concentration (MIC) of 0.025mg/ml was observed for  Staph. aureus  and  Streptococcus pyogenes  with EO of  Origanum vulgare . All the three EOs showed significant anticandida activity. The results related to EOs from  Mentha cervina ,  Ocimum basilicum,  and  Origanum vulgare  demonstrated significant antimicrobial efficacy against drug resistant microorganisms.
