Reginald McKenna (6 July 1863 – 6 September 1943) was a British banker and Liberal politician. He notably served as Home Secretary and Chancellor of the Exchequer during the premiership of H. H. Asquith. His first post under Henry Campbell-Bannerman was as President of the Board of Education. From there he was promoted to the Cabinet as an Imperialist to be First Lord of the Admiralty. As a friend of Asquith his politics were similar; but historians regard his politics as non-Asquithian.
