Abstract Methicillin-Resistant Staphylococcus Aureus (MRSA) is one of the significant pathogens with associated public-health concern in the world. This present study has been focused on the prevalence of MRSA and their antibiotic resistance of indoor and outdoor patients different age and gender in clinical history, Dr. Sirajul Islam medical college and hospital Dhaka, Bangladesh. We were performed during the period of January 2019 to July 2019. A total 964 samples which is outdoor 354 (36.72%) indoor 610 (63.27%). We were observation 5 days (BACTEC-9050 Machine) then inoculated selective onto Blood agar and MacConkey agar media and the culture plates were incubated at 37°C for 24 hrs. The S. aureus colonies showing golden yellow colour on Blood agar were primarily identified as S. aureus, which were then subjected for catalase and coagulase tests. The Methicillin-Resistant Staphylococcus Aureus (MRSA) could be detected only 42 (4.35%) into, males 18 (1.86%) and female 24 (2.48%) in total sample, on the other hand Staphylococci aureus. (MSSA) 50 (5.18%), Pseudomonas spp. 14 (1.45%), Klebsiella spp. 13 (1.34%), Salmonella spp. 27 (2.80%), E. coli 21 (2.17%), No MRSA, MSSA and other organisms are found 797 (82.67%), Standard antimicrobial disks representing multiple sixteen drug were, Sensitive-381 (56.69%), Resistance-284 (42.26%), as well as Intermediate-7 (1.04%) against antibiotics, Oxacillin, Vancomycin, Erythromycin, Co- trimoxazole, Ciprofloxacin, Gentamicin, Linezolid, Amoxicillin, Amoxyclave, Azithromycin,
