Sir James Peiris was a prominent leader in the Sri Lankan independence movement, the first elected Vice-President of the Legislative Council of Ceylon and the first native Governor of Ceylon (Acting).

The Sri Lankan independence movement was a peaceful political movement which was aimed at achieving independence and self-rule for the country of Sri Lanka, then British Ceylon, from the British Empire. The switch of powers was generally known as peaceful transfer of power from the British administration to Ceylon representatives, a phrase that implies considerable continuity with a colonial era that lasted 400 years. It was initiated around the turn of the 20th century and led mostly by the educated middle class. It succeeded when, on 4 February 1948, Ceylon was granted independence as the Dominion of Ceylon. Dominion status within the British Commonwealth was retained for the next 24 years until 22 May 1972 when it became a republic and was renamed the Republic of Sri Lanka.
