Paul Douglas Ackerley (16 May 1949 – 3 May 2011) was a field hockey player from New Zealand. He played right half. He was a member of the national team that won the gold medal at the 1976 Summer Olympics in Montreal. He was selected for the 1980 Summer Olympics, but most sports in New Zealand boycotted the Moscow games so he did not compete. He had 25 international caps for New Zealand.
Ackerley was born in Dunedin but grew up in Ashburton. He graduated from the University of Canterbury, where he played in the Canterbury University hockey club in the late 1960s. He was a secondary school mathematics teacher at Linwood High School, Christchurch and then head of the maths department at Awatapu College, Palmerston North. He transferred to the Education Ministry inspectorate, and then the New Zealand Qualifications Authority, where he was in the group that developed the NCEA. He joined Sport and Recreation New Zealand (SPARC) in 2004 as a senior advisor in coaching and volunteers.
He coached the national woman's hockey team when they won a bronze at the 1998 Commonwealth Games in Malaysia, and the Wellington women’s team.
