Tremandraceae is a botanical name for a family of dicotyledonous plants. A family under this name is widely recognized by plant taxonomy systems, as well as the Cronquist system (1981), with a placement in the order of Polygalales, and the APG system (1998), with a placement in the order of Oxalidales.
It is a small family of a few dozen kinds of woody plants that occur in Australia.
However, the APG II system (2003) does not recognize such a family and takes up these plants in the Elaeocarpaceae family.
