The Battle of Poplar Grove was an incident on 7 March 1900 during the Second Boer War in South Africa. It followed on from the Relief of Kimberley as the British Army moved to take the Boer capital of Bloemfontein. The Boers were demoralised following the surrender of Piet Cronjé at the Battle of Paardeberg. General Sir John French's cavalry attacked the Boer force from the rear while mounted infantry and horse artillery attacked from the right flank. The Boers abandoned their positions in panic before the cavalry. The commander-in-chief of the Free State forces, Christiaan de Wet, in his book called the chapter on the subject "Wild Flight from Poplar Grove".
