Brigadier-General Edmund William Costello, VC, CMG, CVO, DSO (7 August 1873 – 7 June 1949) was a British Indian Army officer and a recipient of the Victoria Cross, the highest and most prestigious award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces.

Costello was born in Sheikhbudia on the North-West Frontier of India, the son of a colonel in the Indian Medical Service.

He was 23 years old, and attached to the 24th Punjab Infantry during the Malakand Frontier War, when the following deed took place for which he was awarded the VC: On 26 July 1897 at Malakand on the Indian Frontier, Lieutenant Costello went out from the hospital enclosure and with the assistance of two sepoys, brought in a wounded lance-havildar who was lying 60 yards (55 m) away, in the open, on the football ground.

This ground was at the time over-run with swordsmen and swept by a heavy fire from both the enemy and our own men who were holding the sapper lines.

In 1913 he entered the Indian Staff College at Quetta and graduated just before the outbreak of the First World War in 1914, when he rejoined his regiment as second-in-command.
