'''''Hydrosaurus''''', commonly known as the '''sailfin dragons''' or '''sailfin lizards''', is a genus in the family [[Agamidae]].<ref name=ReptileDatabase>[http://reptile-database.reptarium.cz/search.php?taxon=&genus=Hydrosaurus&exact%5B%5D=genus&species=&subspecies=&author=&year=&common_name=&location=&holotype=&reference=&submit=Search ''Hydrosaurus''], The Reptile Database</ref> These relatively large lizards are named after the sail-like structure on their tails. They are native to [[Indonesia]] (four species) and the [[Philippines]] (one species), where they are generally found near water, such as rivers and [[mangrove]] swamps.<ref name=Siler2014>Cameron D. Siler, Andrés Lira-Noriega, Rafe M. Brown (2014). Conservation genetics of Australasian sailfin lizards: Flagship species threatened by coastal development and insufficient protected area coverage. Biological Conservation 169: 100–108. {{doi|10.1016/j.biocon.2013.10.014}}</ref> Sailfin lizards are [[semiaquatic]] and able to run short distances across water using both their feet and tail for support, [[Basiliscus (genus)#Running on water|similar to the basilisks]].<ref>Jackman Bauer (2008). Global diversity of lizards in freshwater (Reptilia: Lacertilia). Hydrobiologia 595(1): 581–586.</ref> They are threatened by both [[habitat loss]] and overcollection for the wild-animal trade.<ref name=Siler2014/>

In the 19th century, the genus was called ''Lophura'', but in 1903, Poche pointed out that the name was preoccupied by a [[Gallopheasant|genus of pheasants]].<ref name="Denzer2020" /> Since Günther in 1873, the Sulawesi populations were considered to belong to ''H. amboinensis''; Denzer et al. in 2020 resurrected ''H. celebensis'' and ''H. microlophus'', increasing the number of species from three to five.<ref name="Denzer2020" />

They are the [[Monotypic taxon|only members]] of the subfamily '''Hydrosaurinae'''.
