'''''Odontesthes''''' is a genus of Neotropical silversides. They are found in fresh, brackish and salt water habitats in the southern half of South America (north to Brazil and Peru), as well as the offshore Juan Fernández and Falkland Islands. Additionally, ''O. bonariensis'' has been introduced to other continents.<ref name=USFishWildlifeServices>{{cite web | date=14 July 2014 | url=https://www.fws.gov/fisheries/ans/erss/highrisk/Odontesthes-bonariensis-WEB-7-14-2014.pdf | title=Odontesthes bonariensis Ecological Risk Screening Summary | publisher=U.S. Fish and Wildlife Services | access-date=15 September 2018 }}</ref>
