Jan Willem Spruyt (4 July 1826 in Uithoorn, Netherlands – 8 September 1908 in Inanda, Natal), also known as Jan Willem Spruijt and Jan Willem Landskroon Spruijt (birthname), was a South African civil servant, lawyer and statesman of Dutch descent.
After having spent a few years there, apparently in the service of the government of the Austrian Netherlands, he returned to the Dutch Republic in 1752, where he retired to the village of Maarssen till his death on 13 August 1762 (which may have taken place in the village of Uithoorn).
