The Royal Guard of Oman (RGO) is the royal guard of the Sultan of Oman. It is a separate service within the Sultan's Armed Forces (SAF) and although equipped to carry out land defense operations, it is not part of the Royal Army of Oman. The RGO is a personal security and ceremonial unit responsible for the protection of the Sultan and other senior members of the royal family.

A royal guard is a group of military bodyguards, soldiers or armed retainers responsible for the protection of a royal family member, such as a king or queen, or prince or princess. They often are an elite unit of the regular armed forces, or are designated as such, and may maintain special rights or privileges.
