The Royal Regiment of Horse Guards, also known as the Blues, or abbreviated as RHG, was one of the Cavalry regiments of the British Army, and part of the Household Cavalry. In 1969, it was amalgamated with the 1st The Royal Dragoons to form the Blues and Royals.

Raised in August 1650 by Sir Arthur Haselrig on the orders of Oliver Cromwell, following the 1660 Stuart Restoration, it became the Earl of Oxford's Regiment in 1660. Based on the colour of their uniform, the regiment was nicknamed "the Oxford Blues", or simply the "Blues." In 1750, it became the Royal Horse Guards Blue and eventually, in 1877, the Royal Horse Guards (The Blues).
