Conothamnus is a genus of flowering plants in the family Myrtaceae and is endemic to the south-west of Western Australia.

They are woody shrubs similar to melaleucas but differ in that their leaves are usually arranged in opposite pairs and the maximum number of seeds per fruit is three.

(Melaleucas usually have alternately arranged leaves and there may be hundreds of very fine seeds in each woody capsule.)

Plants in the genus Conothamnus are shrubs with their thinner branches covered with silky hairs.

The flowers are arranged in small heads or spikes in the angles of leaves near the ends of the branches and are a shade of white to yellow.
