Haroutune Krikor Daghlian, Jr., (May 4, 1921 – September 15, 1945) was a physicist with the Manhattan Project, the effort to create atomic bombs during World War II. He accidentally irradiated himself on August 21, 1945, during a critical mass experiment at the remote Omega Site facility at the Los Alamos Laboratory in New Mexico, resulting in his death 25 days later.

Daghlian was irradiated as a result of a criticality accident that occurred when he accidentally dropped a tungsten carbide brick onto a 6.2 kg plutonium-gallium alloy bomb core. This core, subsequently nicknamed the "demon core", was also involved in the death of another physicist, Louis Slotin, in an accident the following year, before it was used in the Operation Crossroads series of nuclear weapon tests.
