Praunus is a genus of mysid shrimp, comprising three species:

• Praunus flexuosus (Müller, 1776)
• Praunus inermis (Rathke, 1843)
• Praunus neglectus (G. O. Sars, 1869)

When originally named in 1814 by William Elford Leach, the genus contained P. flexuosus (the type species), and a second species, "P. integer", which is now known as Neomysis integer.
