Palgrave Macmillan is a British academic and trade publishing company headquartered in the London Borough of Camden.

It maintains offices in London, New York, Shanghai, Melbourne, Sydney, Hong Kong, Delhi and Johannesburg.

Classical historian Sir Francis Palgrave, who founded the Public Record Office, and his four sons were all closely tied with Macmillan Publishers in the 19th century: Palgrave Macmillan publishes The Statesman's Yearbook, an annual reference work which gives a political, economic and social overview of every country of the world.

Palgrave Macmillan represents the sales, marketing and distribution interests of W. H. Freeman, Worth Publishers, Sinauer Associates, and University Science Books outside the US, Canada, Australia and the Far East.

Palgrave has been criticised for a pricing structure which "will limit readership to the privileged few", as opposed to options for "open access without tears" offered by DOAJ, Unpaywall and DOAB.
