Melaleuca serpentina is a plant in the myrtle family, Myrtaceae and is endemic to the Barraba district in Australia. (Some Australian state herbaria continue to use the name Callistemon serpentinus.) It is a shrub with yellow or creamy-green bottlebrush flowers. It is similar to Melaleuca citrina but can be distinguished from that species by its flower colour (red in M. citrina) and its shorter stamens.
