Circaeasteraceae is a family of two species of herbaceous plants native to China and the Himalayas.

The family has been recognized by many taxonomists. The APG II system (2003; unchanged from the APG system of 1998), recognizes it and places it in the order Ranunculales in the clade eudicots. It treats the family to consist of two genera each with a single species,{{cite journal |author1=Christenhusz, M. J. M. |author2=Byng, J.

The APG III system of 2009 also recognizes the two species but no longer allows the optional segregation into Kingdoniaceae.{{Citation |last=Angiosperm Phylogeny Group |year=2009 |title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III |journal=Botanical Journal of the Linnean Society |volume=161 |issue=2 |pages=105–121 |doi=10.1111/j.1095-8339.2009.00996.x |doi-access=free |hdl=10654/18083 |hdl-access=free }}
