Melaleuca comboynensis, commonly known as cliff bottlebrush, is a plant in the myrtle family, Myrtaceae and is endemic to New South Wales and Queensland in Australia. It is usually a shrub, similar to Melaleuca citrina with its hard leaves, spikes of red flowers and clusters of cup-shaped fruits but differs in that its leaves are generally wider and its habitat is usually rocky outcrops rather than along watercourses.
