Meemannia is a genus of extinct bony fish from the early Devonian period.

As preserved, it consists mainly of skull roofing bones and a partial otic region of the braincase.

Its anatomy is unique in a number of features that resemble ray-finned fishes (Actinopterygii), and more generalized jawed vertebrates.

It was described in the May 4, 2006 edition of Nature, and named after Meemann Chang.
