Roderick Edward Maclean (c. 1854 – 8 June 1921) was a Scotsman who attempted to assassinate Queen Victoria on 2 March 1882, at Windsor, England, with a pistol. This was the last of eight attempts by separate people to kill or assault Victoria over a period of four decades. Maclean's motive was purportedly a curt reply to some poetry that he had mailed to the Queen. Other accounts state that the revolver was a toy and that his aim was disrupted by an Eton schoolboy: A poem was later written about Maclean's attempt on the Queen's life by William Topaz McGonagall.
