Hydrosaurus, commonly known as the sailfin dragons or Sailfin lizards, is a genus in the family Agamidae.[2] These relatively large lizards are named after the sail-like structure on their tails. They are native to the Philippines, Indonesia and Papua New Guinea, where they are generally found near water, such as rivers and mangrove.[3] Sailfin lizards are semiaquatic and able to run short distances across water using both their feet and tail for support, similar to the basilisks.[4] They are threatened by both habitat loss and overcollection for the wild animal trade.[3]

They are the only members of the subfamily Hydrosaurinae.
