The Acclamator-class assault ship, alternatively referred to as the Acclamator-class trans-galactic military transport ship or Acclamator-class transgalactic military assault ship, or by the shorter names Acclamator-class transport, Acclamator-class troopship, or the rarer Acclamator I transport, was an assault-class capital ship created for the Galactic Republic by Rothana Heavy Engineering. It was the predecessor of the later Republic and Imperial models in the Star Destroyer line.

The Acclamator-class design was already in development by Rothana and Kuat years before the start of the Clone Wars, and the design was tested as early as 32 BBY. As the Jedi MasterYoda arrived on Kamino to gather an invasion force, dozens of Acclamators had already been built and readied for the soldiers they were designed to carry. In their first engagement at the First Battle of Geonosis, the class proved pivotal in the Republic victory, delivering legions of clone troopers to the battlefield while a large Republic fleet engaged the Separatist fleet in orbit. After delivering their troops, the Acclamators pulled back to provide orbital support, with only a portion of the ships ending up damaged in the battle.

Just after the battle had concluded, the Republic ordered 1,000 more Acclamators based on their success as primary ground force delivery vehicles. All Acclamators were completely crewed by clones, though they would also count regular Republic officers among their crews, as the war ground on. Apart from this, the Acclamators and larger warships were generally off-limits to most regular defense force personnel. During the height of the war, some Acclamators had the paint markings of the Open Circle Fleet like the Venators.

Several different variations were used during the war, with the Acclamator II-class assault ship being the most numerous alternate model. The subclasses saw many battles in both the Clone Wars and the Galactic Civil War. Many were operated to act as mobile depot ships or dedicated clone commando carriers. For the Battle of Muunilinst, the assault ship Nevoota Bee was modified as a carrier, with her hangar decks dedicated to holding 156 V-19 Torrent starfighters. The Victory-class and other Star Destroyers were based on the Acclamator.
