Juncaginaceae is the botanical name of a family of flowering plants. For the past few decades such a family has been recognized by most taxonomists.
The APG II system, of 2003 (unchanged from the APG system, of 1998), also recognizes such a family and places it in the order Alismatales, in the clade monocots. The family includes perhaps four genera (with Triglochin the best known), totalling about a dozen species, which are found in cold or temperate regions in both the Northern and Southern Hemisphere.
