William Murray, Marquess of Tullibardine (14 April 1689 – 9 July 1746) was a Scottish nobleman and Jacobite who took part in the rebellions of 1715, 1719, and 1745.
Attainted for his role in 1715, his younger brother succeeded as Duke of Atholl in 1724, although Tullibardine was made Duke of Rannoch in the Jacobite peerage.
He spent most of his life post 1715 in exile, returning to Scotland only to take part in the rebellions of 1719 and 1745.
In the latter he was one of the Seven Men of Moidart who accompanied Prince Charles to Scotland in July 1745; captured after Culloden in April 1746, he died in the Tower of London on 9 July unmarried and without children.
