Christopher John Pugsley ONZM (born 1947) is a New Zealand military historian.

Pugsley became interested in writing in 1984 when, as a career officer in the New Zealand Army, he worked on a television documentary about New Zealand's involvement in the Gallipoli campaign and authored Gallipoli: The New Zealand Story, which was shortlisted for the Goodman Fielder Wattie Book Award the same year.

During the 1990s he wrote a series of detailed articles called "Walking the Waikato Wars", in the now defunct New Zealand Defence Quarterly, in which he visited each Waikato Battle site and reviewed each battle through the eyes of a modern professional military officer using photographs and maps to illustrate events.

His primary area of interest is 20th-century New Zealand, Australian, Canadian and British Commonwealth military history, with particular focus on Gallipoli, and the Western Front.

In the 2015 New Year Honours, Pugsley was appointed an Officer of the New Zealand Order of Merit, for services as a military historian.
