List of World Championships records in swimming

Below is a list of current championship (or "meet") records for the two World Championships in swimming:

• the swimming events of the World Aquatics Championships, held in a long course (50 meter) pool.
• World Aquatics Swimming Championships (25m), at which swimming is the only discipline. This meet is held in a short course (25 meter) pool.

Both events are organized by the international governing body for aquatics, World Aquatics (formerly known as FINA). These are the fastest times ever swum at any edition of the meet.
