The Mandalore system, alternatively called the Mandalorian system, was a star system situated within the Mandalore sector of the galaxy's Outer Rim Territories, encompassing the planet Mandalore—the homeworld of the Mandalorian people—along with its moon, Concordia, and the planet Kalevala. Despite its formal status as a part of the Galactic Republic, the Mandalore system proclaimed its neutrality during the Clone Wars. It also participated in the Council of Neutral Systems under the leadership of Satine Kryze, the duchess of the New Mandalorians, although Prime Minister Almec actually governed the system.
The initial appearance of the Mandalore system within the new Star Wars canon occurred in "The Mandalore Plot," which was the twelfth episode of Star Wars: The Clone Wars' second season, a canon animated series. Its original broadcast took place on January 29, 2010. The Star Wars Legends reference book titled The Empire Strikes Back Sketchbook, authored by Joe Johnston and Nilo Rodis-Jamero and published in June, 1980, contained its first mention.
