Mesoveliidae is a family of water treaders in the order Hemiptera.

There are about 16 genera and at least 50 described species in Mesoveliidae.

[1][2][3][4] These 12 extant genera belong to the family Mesoveliidae.

While traditionally divided in two subfamilies, Madeoveliinae (including Madeovelia and Mesoveloidea) and Mesoveliinae (all other genera), molecular phylogenetics suggests Mesoveliinae are polyphyletic and thus the subfamily-level classification should be abandoned.
