List of seaplane bases in the United Kingdom

This article lists both active and historic seaplane bases in the United Kingdom, many of which were either used for, or planned to be used for, the defence of the UK.

A seaplane base may be anything from a stretch of water where seaplanes were based to a full installation, either floating (powered or unpowered) or shore based, where seaplanes were serviced. In the UK these are presumed to be coastal.
