The King's Guard is a ceremonial designation given by the Monarchy of Thailand to the various units within the Royal Thai Armed Forces. Practical and real security of the Royal family has since 1992 been provided by the Royal Security Command, which is an agency that is completely independent of the armed forces.

The Royal Security Command is the king of Thailand's military household and is part of Thailand's royal court administration. It exercises command and control over the military units that are engaged full-time in the protection and guarding of the king and his family as well as the various Royal palaces of Thailand.
