Christopher Joseph Walker CF(10 July 1942 – 18 April 2017) was a British historian and author.

Walker was educated at Lancing College and Brasenose College, Oxford.

He worked in Sotheby's department of historical and literary manuscripts. After winning a Winston Churchill Travelling Fellowship in 1971 he wrote a book on Armenian history which was reissued in 1990. In 1975 with the support of "Minority Rights Group" he published "The Armenians" report (co-author - prof. David Marshall Lang).^[1] In November 1989 at Oxford University Walker had a lecture on the modern history of Armenia. He also wrote several books and articles on the history of Armenia, including the book Armenia: The Survival of a Nation, which has been described as an "excellent history of Greater Armenia"^[2] and "a balanced presentation" of the events during the Armenian genocide of 1895–1918.^[3]

After a long-time research in archives, in 2003 Walker completed his book, Life of Oliver Baldwin, about a soldier, statesman, and journalist, the son of a Conservative Prime Minister, who became a Labour member of British Parliament.
