The Myrtales are an order of flowering plants placed within the rosid group of dicotyledons. The following families are typical of newer classifications:

• Family Alzateaceae
• Family Combretaceae
• Family Crypteroniaceae
• Family Heteropyxidaceae
• Family Lythraceae (loosestrife family)
• Family Melastomataceae
• Family Memecylaceae
• Family Myrtaceae (Myrtle family)
• Family Oliniaceae
• Family Onagraceae (evening primrose family)
• Family Penaeaceae
• Family Psiloxylaceae
• Family Rhynchocalycaceae
• Family Vochysiaceae

The older Cronquist system gives essentially the same composition, except the Vochysiaceae are removed to the order Polygalales, and the Thymelaeaceae are included. The families Sonneratiaceae , Trapaceae, and Punicaceae are removed from the Lythraceae, while the Psioxylaceae and Heteropyxidaceae are treated within the Myrtaceae, and the Memecyclaceae within the Melastomataceae.
