General Sir William Jones, GCB (1808 – 8 April 1890) was a Welsh soldier who was a senior officer in the British Army.

After Goojerat, in command of his regiment and a troop of Bengal horse artillery, he pursued the enemy to the Khyber Pass, for which he was made a C.B.

During the Indian Mutiny Jones commanded the 3rd infantry brigade at the Siege of Delhi and was one of the five officers selected to lead the storming parties on 14 September 1857.

When the assault was made he held command of both the first and second columns following the death from wounds of Brigadier-General Nicholson, and remained in charge during the six days of fighting in the streets.

In 1857 he had married Elizabeth (died 12 November 1885), the second daughter of John Tuthill of Kilmore House, County Limerick.
