Diacyclops uruguayensis is a species of freshwater copepod belonging to the family Cyclopidae.

[1][2] This is part of the genus Diacyclops, which includes numerous species of freshwater copepods.

It was originally described from pools near Montevideo, Uruguay.

Subsequent studies have recorded its presence in other regions, including parts of Brazil, such as Santa Catarina and Ceará, suggesting a broader distribution than initially recognized.
