The aim of this research was to show the profile of S. aureus bacteria isolated from fresh milk at four dairy farms in Surabaya against antibiotics Oxacillin, Penicillin, Amphicillin, Cefoxitin, and Tetracyclin. The study used purposive sampling method. About 40 samples were isolated on Mannitol Salt Agar media (MSA) from the result which identified as Staphylococcus sp was 23, then the positive result of 23 samples were tested using gram staining, the positive result of 20 sample catalase test, and then 14 (35%) samples showed the positive sample of S. aureus on coagulase test. Antibiotic disk used i.e Oxacillin, Penicillin, Amphicillin, Cefoxitin and Tetracylin by using Kirby Bauer method. Inhibiton diameter zone measured at millimeter to determine a sensitivity level of antibiotic. The result showed that 14 (100%) samples were resistant to Cefoxitin, 14 (100%) samples were resistant to Penicillin, 12 (85,7%) samples were resistant and 2 (14,3%) samples were sensitive to Amphicillin, 8 (57,2%) of samples were sensitive and 6 (42,8%) was intermediet to Tetracyclin, and 9 (64,2%) of samples were resistant and 5 (35,8%) samples were sensitive to Oxacillin
