Rooibos (Anglicized pronunciation: /ˈrɔɪbɒs/ ROY-bos; Afrikaans pronunciation:[rɔːibɔs], meaning "red bush"; scientific name Aspalathus linearis) is a broom-like member of the legume family of plants growing in South Africa's fynbos.

The generic name comes from the plant Calicotome villosa, aspalathos in Greek. This plant has very similar growth and flowers to the rooibos plant. The specific name linearis comes from the plant's linear growing structure and needle-like leaves.
