The Urussig were a Klingon familial line extant in the 23rd century. Many of the Urussig line were of partial Romulan heritage.

A Klingon woman who joined the Sheridan's World colony as security chief was a member of the Urussig line. Her name was Kaziri sutai-Urussig. (FASA RPG module: Conflict of Interests)

One member of this line was Kvel zantai-Urussig, a part-Romulan captain who was assigned to IKS Wings of Destruction in the 2270s. (FASA RPG module: The White Flame Starship Combat Scenario Pack)
