Syd Jackson (1939 – 3 September 2007) was a prominent Māori activist, trade unionist and leader.
Syd Jackson, of Ngāti Kahungunu and Ngāti Porou descent, first came to prominence at the University of Auckland, where he gained an MA. He was the chairman of the Māori Students Association, and then was a founder of Ngā Tamatoa. He was strongly involved in supporting Tino Rangatiratanga, the revival of the Māori language, and the Māori protest movement in general. He was the son of the All Black Everard Jackson, and grandson of New Zealand Kiwis representative Frederick Stanley Jackson. He was active since 1968 against apartheid, particularly New Zealand tours of South Africa.
Syd Jackson was deeply involved in the trade union movement in the 1980s, as a field officer and then as secretary of the Clerical Workers Union for 17 years.
He was also chairperson of Te Kupenga o Hoturoa - the first Māori sponsored primary healthcare organisation; a Director of Te Roopu Huihuinga Hauora, a Māori healthcare organisation, and built up Turuki Healthcare as its CEO.
Jackson was first married to the late Hana Te Hemara, and was survived by Deidre Jackson.
