The Cularin Spacer's Union was an organization that operated in the Cularin system during the waning years of the Galactic Republic. During the Clone Wars, a number of members of the Union attended a peace conference on the planet Cularin, which had been organized by the Human Gavid Lermyn. Later, the Union sent a representative—Quinlu Naj–to represent then at the Cularin Trade Show, a trade show that was held by the Cularin Trade Alliance aboard the starship TAV Prosperity.
