James Daniel "BJ" Bjorken (June 22, 1934 – c. August 2024) was an American theoretical physicist. He was a Putnam Fellow in 1954,^[1] received a BS in physics from MIT in 1956, and obtained his PhD from Stanford University in 1959. Bjorken was a visiting scholar at the Institute for Advanced Study in the fall of 1962.^[2] He was also emeritus professor in the SLAC Theory Group at the Stanford Linear Accelerator Center, and was a member of the Theory Department of the Fermi National Accelerator Laboratory (1979–1989).

Bjorken was awarded the Dirac Medal of the ICTP in 2004; and, in 2015, the Wolf Prize in Physics and the EPS High Energy and Particle Physics Prize.^[3]
