The Royal Life Guards (Danish: Den Kongelige Livgarde) is a mechanized infantry regiment of the Royal Danish Army, founded in 1658 by King Frederik III. The primary task is to provide a number of soldiers from the Guard Company to serve as a guard/ceremonial unit to the Danish monarchy, while training the Royal Guards for various functions in the mobilisation force. Until its disbandment, the Royal Horse Guards (Danish: Livgarden til Hest), served the role as the mounted guard/ceremonial unit, afterwards the role was taken over by Guard Hussar Regiment Mounted Squadron. During the time period 1684–1867, the Royal Life Guards were called The Royal Foot Guard (Danish: Den Kongelige Livgarde til Fods), in order to distinguish between the regiment and the Royal Horse Guards.

The Royal Life Guards were established by Frederik III of Denmark on 30 June 1658, the guards were both to protect Frederik and to be a combat troop regiment.

The Royal Life Guards serve as a front-line unit and as a guard/ceremonial unit as well to the Danish monarchy. They were the major security force for the Danish Royal family at their personal estates. They would play a role in international peace keeping due to Denmark's involvement with NATO. The unit might be deployed internationally for peace keeping efforts.

The regiment consists of two infantry battalions, the Guard Company and the Musical Corps:
