Amborellaceae is the botanical name of a family of flowering plants. Such a family has been recognised by many taxonomists, at least after the plants were discovered, which was relatively recently.

The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognise such a family and leaves it unplaced as to order. It is not placed at all beyond being accepted as the most basic lineage in the clade angiosperms. The family consists of only a single species, Amborella trichopoda of New Caledonia.
