Babylon 5 is an American science fiction television series created, produced and largely written by J. Michael Straczynski. The show centers on the Babylon 5 space station: a focal point for politics, diplomacy, and conflict during the years 2257–2262. With its prominent use of planned story arcs, the series was often described as a "novel for television".

Unique to the Babylon 5 universe among virtually all other shared universes is the sanctioned canonicity of many of its offshoot novels and comic book stories; nearly all of the Babylon 5 novels and novelizations to date having been based on outlines written directly by J. Michael Straczynski.
