Hector Wilfred Jayewardene (1916–1989) was one of the leading advocates of his generation at the Ceylon bar, and the brother of President J.R. Jayewardene.
He took silk as a Queen's Counsel and practised principally in criminal and constitutional law. He appeared in a number of the most significant cases of the post-independence period, and served on international legal bodies including as a member of the International Commission of Jurists. He held no ministerial office, and is included here for a legal rather than a political career.
