This is a list of events that occurred in the 2280s:
- Friday, January 14th, 2281
- John Sheridan's life force from Lorien finally ceases. He takes a Snub-nose Whitestar to Coriana VI, in a way following the Minbari tradition of "going to the sea".

It is believed that he was taken beyond the rim of the galaxy, not into death, but rather to dwell with the First Ones until humanity itself passed beyond the rim.
- On Earth, upon hearing an ISN report on the death of John Sheridan, Alfred Bester passes away in his jail cell.
- Babylon 5 is demolished by Earthforce due to waning traffic over the years.
