Putnam's Monthly Magazine of American Literature, Science and Art was a monthly periodical published by G. P. Putnam's Sons featuring American literature and articles on science, art, and politics.

[2] First, it was edited by Charles Frederick Briggs from January 1853 to September 1857 (whereupon it merged with Emerson's United States Magazine); It was founded by George Palmer Putnam, who intended it to be a vehicle for publishing the best of new American writing; a circular that Putnam sent to prospective authors (including Herman Melville) announced that the magazine would be 'as essentially an organ of American thought as possible'.

As publishing only American writing would distinguish Putnam's from Harper's and give the former unique status in the marketplace, Ezra Greenspan has argued that the magazine's literary nationalism was ‘a shrewd mixture of ideological altruism and publishing acumen’.

[4] Frederick Law Olmsted and George William Curtis served as its owners and editors in its final two years.

[5] Edited by C. F. Briggs, Edmund Clarence Stedman and Parke Godwin from January 1868 to November 1870, whereupon it merged with Scribner's Monthly.
