The Vithrel-class was a type of starship planned to be used by the Romulan Star Empire's Star Navy in the 24th century. The Vithrel-class was designed as a swift bird-of-prey design that, by the turn of the 2370s decade, was due to enter service around the year 2376. Upon commission, this would be the first bird-of-prey class created in the later 24th century, with the previous vessel of that type, the Ganum-class, having been created decades earlier.

- This class presumably included a prototype ship that would be named Vithrel, although no such ship was mentioned.
