Shawn Mackay (31 May 1982 – 6 April 2009) was an Australian rugby union player with the Canberra based Brumbies in the Super 14 competition.

Mackay began playing rugby as a 6-year-old for the Clovelly Sea Eagles, alongside great friend and former Wallabies vice Captain Morgan Turinui.

These two great mates played together in the Waverley College First XV, along with Mackay's fellow Brumbies teammates Stephen Hoiles and Patrick Phibbs.

While crossing the road to board the team bus, Shawn was hit by the driver of an armed response vehicle.

One of the first people to attend to Mackay was Sharks prop Jannie du Plessis, a practising doctor, who was with the Brumbies group at the time.

Du Plessis contacted emergency services and helped Mackay breathe while awaiting their arrival.

A Minutes Applause was held in Mackay's honour for the Brumbies emotional homecoming against the Stormers on 11 April 2009.
