Sir Waithilingam Duraiswamy was a Ceylon Tamil lawyer, politician and speaker of the State Council of Ceylon.

The Legislative Council of Ceylon was the legislative body of Ceylon established in 1833, along with the Executive Council of Ceylon, on the recommendations of the Colebrooke-Cameron Commission. It was the first form of representative government in the island. The 1931 Donoughmore Constitution replaced the Legislative Council with the State Council of Ceylon.
