Blackwood's Magazine was a British magazine and miscellany printed between 1817 and 1980. It was founded by the publisher William Blackwood and was originally called the Edinburgh Monthly Magazine. The first number appeared in April 1817 under the editorship of Thomas Pringle and James Cleghorn. The journal was unsuccessful and Blackwood fired Pringle and Cleghorn and relaunched the journal as Blackwood's Edinburgh Magazine under his own editorship. The journal eventually adopted the shorter name and from the relaunch often referred to itself as Maga. The title page bore the image of George Buchanan, a 16th-century Scottish historian, religious and political thinker.

William Blackwood was a Scottish publisher who founded the firm of William Blackwood and Sons.
