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 Star Wars: The Ultimate Visual Guide mentions that the starships and vehicles used by the Republic during the Clone Wars, such as the Acclamator and AT-TE, were «retired» shortly after the end of the conflict. This is inconsistent with what is shown in the post-Revenge of the Sith era, such as Star Wars: Empire at War and the Star Wars: Empire comic series, where they are shown to be in continued use, albeit on the Empire’s more remote worlds. In the case of the Acclamator, some are specifically mentioned as «slave ships» by Darth Vader in the In the Shadows of Their Fathers story arc. Starships of the Galaxy (Saga Edition) clarified that Acclamators were used by forces in backwater areas.

In the game Star Wars: Empire at War and Star Wars: Battlefront II, the Acclamators present seem geared towards ship-combat rather than carrying ground forces, and are designated as frigates. The 2007 edition of Starships of the Galaxy states a crew of 20,141 and a hyperdrive rating of 0.75 for both Acclamator classes, contradicting the respective numbers of 700 and 0.6 given by Star Wars: Attack of the Clones Incredible Cross-Sections and Star Wars: Complete Cross-Sections. Incredible Cross-Sections states that the Acclamator’s bridge was windowless; visuals are obtained via screens or holographic displays. However various comics and the Clone Wars series depict the vessel with Star Destroyer style trapezoidal window arrays.
