Oritavancin, sold under the brand name Orbactiv (by Melinta Therapeutics) among others, is a semisynthetic glycopeptide antibiotic medication for the treatment of serious Gram-positive bacterial infections. Its chemical structure as a lipoglycopeptide is similar to vancomycin.

The U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have approved oritavancin for treatment of acute bacterial skin and skin structure infections.
