The Basra Memorial commemorates more than 40,500 members of the Commonwealth forces who died in Mesopotamia (Iraq) from 1914 to 1921 and whose graves are not known.

It was designed by Edward Warren and unveiled by Sir Gilbert Clayton on 27 March 1929.

The campaign in Mesopotamia was largely fought by the Indian Army, and so the majority of those commemorated on the memorial are Indian troops. Some were killed in battle, others died of wounds or sickness, and many died while in captivity in Ottoman prisoner of war camps.
