Cynoglossus is a genus of fish in the family Cynoglossidae. Most species are indigenous to the Indo-Pacific region, but there are also a few in warmer parts of the East Atlantic. They are commonly found in shallow waters on a muddy or sandy bottom, including estuaries and a few species are restricted to fresh water. One species Cynoglossus sinusarabici has invaded the Mediterranean Sea through the Suez Canal from the Red Sea, a process known as Lessepsian or Erythrean migration.

It is a demersal species found at depths of 10-300m, it has been found in brackish water, but is normally a coastal species which occurs over substrates of sand or mud. It feeds on small fish and crustaceans. This species is targeted in trawl fisheries throughout its range and in many areas, it appears to have undergone significant declines. For example, in Gabon the mixed Cynoglossus stock is considered overexploited, while in other parts of western Africa such as Mauritania the stocks of Cynoglossus had declined by over 60% in the five or six years up to 2015.
