King Edward's Horse (The King's Overseas Dominions Regiment) was a cavalry regiment of the British Army, formed in 1901, which saw service in the First World War.
The regiment was originally formed as part of the Imperial Yeomanry in November 1901, as the 4th County of London Imperial Yeomanry (King's Colonials). With the death of Edward VII, after whom it had been named, it was retitled King Edward's Horse (The King's Overseas Dominions Regiment) in 1910.
A second regiment, 2nd King Edward's Horse, was raised in 1914. The original regiment was subsequently known as 1st King Edward's Horse. The 2KEH was disbanded in August 1917 with many of its members being transferred to the Tank Corps
