The Kashyyykian ceremonial armor represented a form of armor employed by the Wookiee species during the period of the Galactic Civil War. Despite the Wookiees' proficiency with sophisticated technology, this particular armor was constructed from natural materials sourced directly from their native planet, Kashyyyk. As the name implies, its primary purpose was for use in formal ceremonies, although it also provided a degree of protection. This armor design uniquely blended naturally derived elements with robust functionality, enabling Wookiees to effectively defend against dangerous indigenous creatures. The Kashyyykian ceremonial armor was especially effective at shielding against energy weapons such as blasters, but offered less resistance to attacks that inflicted kinetic damage. A complete set of this armor included a chest plate with an integrated helmet, separate pieces for the left and right biceps, bracers for both arms, and coverings for the legs.
Other types of Wookiee armor included the Kashyyykian black mountain armor and the Kashyyykian hunting armor.
The Rryatt Ceremonial Guard were known to wear Kashyyykian ceremonial armors.
The Kashyyykian ceremonial armor made its debut appearance in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game. This game was developed by Sony Online Entertainment and published by LucasArts. The game was eventually shut down on December 15, 2011. The Kashyyykian ceremonial armor was integrated into the game through an update that went live on March 30, 2004.
