Dr. Ding Lik-kiu (Chinese: 陳立僑, 1921 in Raj of Sarawak – 24 June 2008 in San Francisco, United States) was a prominent Hong Kong social activist in the 1970s and 80s.
Ding was taken in by the local Methodist missionary school and through a series of scholarships eventually studied medicine at Johns Hopkins University in Baltimore and then went back to Borneo to serve as a medical missionary, where he helped set up Christ Hospital.
A methadone outpatient scheme, which Ding had advocated since the late 1960s backed up by results from Randomized control trial, was set up in 1972 by the Medical Health Department.
He even opposed to the performance of the Rolling Stones in Hong Kong because of their past association with drugs.
He led a seven-member delegation to London in May 1984 to lobby for democratic reform in Hong Kong before the colony's handover to China and met with the former British Prime Minister Edward Heath.
