Hypoxidaceae is the botanical name of a family of flowering plants. Such a family has not been recognized by many taxonomists.

The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family and places it in the order Asparagales, in the clade monocots. The family consist of probably over half-a-dozen genera totalling some one hundred to two hundred species.

The members of the family are small to medium herbs, with grass-like leaves and an invisible stem, modified into a corm or a rhizome. The flowers are born on leafless shoots, also called scapes. The flowers are trimerous, radially symmetric. The ovary is inferior, developing into a capsule or a false berry.
