Teixobactin (/ˌteɪksoʊˈbæktɪn/) is a peptide-like secondary metabolite of some species of bacteria, that kills some gram-positive bacteria. It appears to belong to a new class of antibiotics, and harms bacteria by binding to lipid II and lipid III, important precursor molecules for forming the cell wall.

Teixobactin was discovered using a new method of culturing bacteria in soil, which allowed researchers to grow a previously unculturable bacterium now named Eleftheria terrae, which produces the antibiotic. Teixobactin was shown to kill Staphylococcus aureus and Mycobacterium tuberculosis.
