See text Liagoraceae is a family of red algae (Rhodophyta) in the order Nemaliales.

It was originally called Helminthocladiaceae by J.Agardh in 1851, but P. Silva in 1980 stated that this was predated by Liagoraceae which was published in 1843.

[4] The family was found to be polyphyletic (having a mixed evolutionary origin) based on analyses of rbcL enzymes.

The 2 genera of Yamadaella and Liagoropsis, which were previously placed in the Dermonemataceae family, were found to have independent lineages and could be recognized as two new families Yamadaellaceae and Liagoropsidaceae.
