The ORB-01 Akatsuki Gundam (aka Akatsuki Gundam, Akatsuki) is a Mobile Suit introduced in the anime Mobile Suit Gundam SEED Destiny. It is initially piloted by Cagalli Yula Athha using the "Oowashi" Sky Pack, and later by Mu La Flaga using the "Shiranui" Space Pack.

The Akatsuki Gundam was developed through the fusion of the knowledge that the Orb engineers had gained from studying the GAT-X105 Strike Gundam and its Striker Pack support system, with newer Orb-based prototype technologies. Its standard armaments include a twin beam saber, head-mounted CIWS, an arm-mounted shield, and a beam rifle. Its most remarkable feature is its gold-colored armor, known as the Yata-no-Kagami. Gold is the color reserved for Orb's ruling class, and this armor is actually a mirror surface armor capable of deflecting and even reflecting beam fire with help from the Akatsuki's sensors, making the mobile suit virtually impervious to beam shots. Despite this, its vulnerability to melee and physical weapons remained equal to that of any other mobile suit, hence the presence of a shield as part of its armaments.

The Akatsuki can also equip two optional backpacks, which are derived from the Strike Gundam's Striker Packs, to improve its combat abilities. On Earth, it can use an aerial backpack known as "Oowashi" Sky Pack, granting it atmospheric flight capabilities. Armed with two beam cannons, the Oowashi can separate from the mobile suit and transform into a support aircraft, similar to the ZGMF-X09A Justice Gundam's Fatum-00. With this pack on, the suit is known as Oowashi Akatsuki Gundam. When operating in space, the Akatsuki can use another backpack known as the "Shiranui" Space Pack, which increases the suit's mobility and equipped it with seven remote control beam turret units that have offensive and defensive capabilities. With this pack on, the suit is known as Shiranui Akatsuki Gundam.
