Sir William Davidson, 1st Baronet of Curriehill, (Dundee, 1614/5 – Edinburgh, c. 1689) was a Scottish tradesman in Amsterdam, an agent and a spy for the King and a member of his Privy Council.

[3] In July 1660 Mary Stuart lived in his house on Herengracht,[clarification needed] to settle an agreement with the Amsterdam burgomasters on the education of her grandson William III of Orange, only ten years old.

It was presented by a consortium of Dutch sugar merchants,[5][6] to King Charles II of England in 1660 to mark the occasion of his Restoration to the throne.

[7] In 1662 he was appointed as the King's agent in Amsterdam; he had already been knighted as a baronet by Charles II and in 1661 as the conservator of the staple in Veere.

From 1664 he mined for iron at Mostadmark (in the present-day Malvik Municipality), east of Trondheim with permission for 20 years from Frederik III of Denmark and Hannibal Sehested (governor) of Norway.

On 14 October 1670 he was allowed to start mining for copper near Klæbu, south of Trondheim, according to a letter from King Christian IV of Denmark.

[13] Davidson spent the remaining of his life in settling legal battles against a host of complaints from the Trondheim civic and mercantile society.
