Palgrave Macmillan is an international academic and trade publishing company. Its programme includes textbooks, journals, monographs, professional and reference works in print and online.

Palgrave Macmillan was created in 2000 when St. Martin's Press Scholarly and Reference in the USA united with Macmillan Press in the UK to combine their worldwide academic publishing operations. The company was known as simply Palgrave until 2002, but has since been known as Palgrave Macmillan.

It is a subsidiary of Springer Nature. Until 2015, it was part of the Macmillan Group and therefore fully owned by the German publishing company Holtzbrinck Publishing Group. As part of Macmillan, it was headquartered at the Macmillan campus in Kings Cross London with other Macmillan companies including Pan Macmillan, Nature Publishing Group and Macmillan Education, having moved from Basingstoke, Hampshire, England, United Kingdom in 2014.
