The aim of this study was to inveftigate antibacterial extract etanol  of Porifera (Spongia officinalis)against the growth of Staphylococcus aureus ATCC 25923.Present study was an experimental in vitro test. Antibacterial activity assays were carried out by the disc diffusion method. Antibacterial activity was determined by the clear zone formed around the papaer disc and minimum inhibitor concentration which could inhibit the growth of Staphylococcus aureus ATCC 25923.The results are supported by the presence of secondary metabolite by phytochemical test such as alkaloid, terpenoid, steroid, saponin and tanin.Extract ethanolof Spongia officinalis. Extract etanol Spongia officinalishas antibacterial activity againts Staphylococcus aureus ATCC 25923.
