Don Carolis Hewavitharane Wijeyaguneratne (Sinhala: දොන් කරෝලිස් හේවාවිතාරණ)(1833 – 18 February 1906) was a Ceylonese businessman, industrialist, philanthropist and a pioneer of the Buddhist revival movement.

The couple had five children, Don David Hewavitharana, who later changed his name to Anagarika Dharmapala and became a prominent figure Buddhist revival movement in Ceylon and in India; Dr C.A.Hewavitharana, a prominent physician and independence activist; Edmund Hewavitarne; Simon Alexander Hewavitharana, and Dona Engeltina Moonesinghe.

By the turn of the century, the firm was exporting to Australia, South Africa, India, Burma, the UK, Europe & the USA.

This was changed after Col. Henry Steel Olcott made representations to Secretary of State for the Colonies in London on behalf of the Buddhists of Sri Lanka.

The British had not shown any interest in restoring the Vesak holiday, which the Buddhists lost in 1770 during the period of Dutch rule.
