Trilakas (also spelled Trilakis) was a city on the Romulan planet Artaleirh, located in a mountainous region near the center of one of the world's major populated continents. It consisted largely of rounded, one-story clay houses.

In 2156, the Haakonans attacked and leveled the Trilakis settlement. (ENT novel: Beneath the Raptor's Wing)

The USS Aventine made a delivery of emergency food supplies to Trilakas in 2381, in the aftermath of that year's Borg Invasion. (ST novel: A Singular Destiny)
