The Romulan ranking system was a hierarchical collective command structure used within the Romulan Star Empire, seemingly descended from the ancient Vulcan ranking system which was also used by the Vulcan military forces until the mid-22nd century. The Tal Shiar used a different ranking system, although they were at times used interchangeably with the military ranks.

Though not part of the Romulan rank hierarchy, the title captain has been used in the Empire, but not in terms of rank. Doctor Telek R'Mor, a low ranking scientist and minor functionary from the Romulan Astrophysical Academy, initially referred to himself as "captain of the cargo vessel Talvath."

According to The Making of Star Trek (p. 256) the Romulan rank of centurion is the generic rank of all officers.
According to deleted lines from the script for "The Enemy", in a bit of sarcastic banter, Lieutenant Commander Geordi La Forge, upon learning the identity of the soldier, Centurion Bochra, who he was otherwise calling "commodore", he stated, "And you're a centurion. Well, stay with it, you'll be a commodore someday." Bochra, catching on to La Forge's sarcasm, fired back with, "I'm not certain of the equivalent Federation rank… but I do know it's higher than lieutenant commander."

Background information

Given the rank of sublieutenant, there is presumably a lieutenant rank at some point in the Romulan military history. No Romulan has been referred to as a "Lieutenant" in Star Trek.

The ranks of centurion and uhlan are ancient Earth ranks (Roman and Polish respectively) not known to be used by any other Star Trek cultures. The reason for their use in the Romulan language or by the universal translator is unknown.
