Diapensiaceae is a small family of flowering plants, which includes 15 species in 6 genera.

[7] Past literature classified Diapensiaceae as an old family, without defining the meaning of old.

[9][10] The family, originally including only Diapensia lapponica, was named by Heinrich Friedrich Link in 1829.

[11] Concerning the interrelationships in Diapensiaceae, debate still remains regarding the recognition of Schizocodon and whether it should be separate from Shortia.

[19] Family Diapensiaceae members are mostly found in North America and Eastern Asia.
