Hydromedusa, commonly known as the South American snake-necked turtles, is a genus of turtles in the family Chelidae. They are quite closely related to the South American side-necked swamp turtles (Acanthochelys) and the snake-necked turtles of the Australian-Melanesian region (Chelodina), but less closely to the spine-necked river turtles of South America (Podocnemididae) which belong to a more modern lineage of Pleurodira.

This genus contains the following three species:

• †Hydromedusa casamayorensis De la Fuente & Bona 2002 - Salamanca and Sarmiento Formations, Argentina
• Hydromedusa maximiliani Mikan 1820 - Brazilian snake-necked turtle
• Hydromedusa tectifera Cope 1869 - Argentine snake-necked turtle
