Triuridaceae is a family of flowering plants. Such a family has been recognized by relatively few taxonomists.

The APG II system, of 2003, does recognize such a family and places it in the order Pandanales, in the clade monocots. This is a change from the APG system, of 1998, which left the family unplaced as to order, but did place it in the clade monocots.

Most sources assume the family to consist of some half dozen genera, with Sciaphila as the biggest genus. However, H. Maas-van de Kamer and T. Weustenfeld (1998) regarded the family to consist of the following nine genera :

• Andruris Schltr.
• Hyalisma Champ.
• Lacandonia E.Martínez & Ramos
• Peltophyllum Gardner (syn. Hexuris Miers)
• Sciaphila Blume (syn. Hyalisma Champion)
• Seychellaria Hemsl.
• Soridium Miers
• Triuridopsis H.Maas & Maas
• Triuris Miers

The Kew "World Checklist of the Triuridaceae" was reviewed by H. Maas-van de Kamer and P. Maas-van de Kamer in 2005. In this list the genera Andruris and Hyalisma are synonymized into Sciaphila, but two new genera Kupea and Kihansia are included. Both genera were described (and placed in Triuridaceae) in 2003. The revised list of genera is thus:

• Kihansia Cheek
• Kupea Cheek & S.A.Williams
• Lacandonia E.Martínez & Ramos
• Peltophyllum Gardner (syn. Hexuris Miers)
• Sciaphila Blume (syn. Hyalisma Champion)
• Seychellaria Hemsl.
• Soridium Miers
• Triuridopsis H.Maas & Maas
• Triuris Miers
