The list of British 800 metres athletics champions covers four competitions;
The AAA Championships were open to international athletes but a guest international was not considered the National Champion in this list if they won the relevant Championship, that title going to the highest placed British athlete in the event. Despite this, the AAA Championships were regarded as more prestigious than the British-only UK Championships event for most of the latter's existence, although both were recognised as national championships. The UK Championships were ended in 1997, while the AAA Championships were supplanted by the British Athletics Championships in 2007. While the AAA Championships continue, they are no longer regarded as crowning a British champion.
