Sir William McNair Snadden, 1st Baronet

Sir William McNair Snadden, 1st Baronet JP (15 January 1896 – 23 November 1959) was a Scottish Tory politician.

The youngest son of the Reverend James Snadden, the young Snadden was educated at Dollar Academy. In 1915, early in the Great War, he was commissioned into the Argyll and Sutherland Highlanders and served with the British Expeditionary Force in France between 1915 and 1917.

Snadden was elected as the Unionist Member of Parliament for Kinross and West Perthshire at a by-election in 1938, following the resignation of Katharine Marjory Stewart-Murray, Duchess of Atholl, who had left the Scottish Unionist Party in protest against the National government's European policy, and who stood again as an Independent; retaining the seat only narrowly, Snadden held it until he stood down at the 1955 general election. He was joint Parliamentary Under-Secretary of State for Scotland from 1951 to 1955.

He was Chairman of the Scottish Food Hygiene Council, President of the Smithfield Club, and President of the Scottish Unionist Association. He was a keen farmer and stock breeder in Perthshire.

On his retirement he was created a baronet. The baronetcy became extinct on his death.
