Field Marshal Frederick Sleigh Roberts, 1st Earl Roberts, (30 September 1832 – 14 November 1914) was a British Victorian era general who became one of the most successful British military commanders of his time. Born in India to an Anglo-Irish family, Roberts joined the East India Company Army and served as a young officer in the Indian Rebellion during which he was awarded the Victoria Cross for gallantry. He was then transferred to the British Army and fought in the Expedition to Abyssinia and the Second Anglo-Afghan War, in which his exploits earned him widespread fame. Roberts would go on to serve as the Commander-in-Chief, India before leading British Forces for a year during the Second Boer War. He also became the last Commander-in-Chief of the Forces before the post was abolished in 1904.

A man of small stature, Roberts was affectionately known to his troops and the wider British public as "Bobs" and revered as one of Britain's leading military figures at a time when the British Empire reached the height of its power. He became a symbol for the British Army and in later life became an influential proponent of stronger defence in response to the increasing threat that the German Empire posed to Britain in the lead up to the First World War.
