2015 IPC Swimming World Championships – Mixed 4 x 50 metre freestyle relay

The Mixed 50 metre x 4 freestyle at the 2015 IPC Swimming World Championships was held at the Tollcross International Swimming Centre in Glasgow, United Kingdom from 13-17 July.

As with other disability relay events, the freestyle works on a points system whereby the classification numbers of each swimmer are totaled to give a number no higher than 20. This was the first time the World Championships have included a mixed sex event, after its successful introduction in the 2014 IPC European Swimming Championships. The race requires each team to be made up of two male and two female competitors.
