Marvin Hunter McIntyre (November 27, 1878 – December 13, 1943) was an American journalist and Presidential Secretary to President Franklin D. Roosevelt (FDR).

McIntyre was born in La Grange, Kentucky, 27 November 1878 and was educated at the Wall and Mooney Preparatory school in Franklin, Tennessee, and at Vanderbilt University.

In 1920 when FDR ran for vice president with James M. Cox, the Democrat's presidential nominee, McIntyre shared day-to-day campaign responsibilities with Steven T.

[3] After the Democratic defeat in 1920, he remained in Washington DC, contributing articles to Army and Navy Journals and later becoming representative of the Pathé News Reel Company.

He stayed in the motion picture business until 1931 when the Roosevelt-for-President drive began to gather momentum and FDR, then Governor of New York, called McIntyre to join him in Albany to start plans for the campaign.

[4][2] Historian Arthur Schlesinger, Jr. described McIntyre and his co-worker Early, also an assistant secretary, as being "aggressively non-ideological:" Both men's loyalty was to FDR rather than to his political philosophy.

[10][11][12][13] McIntyre remained in the position of the President's Correspondence Secretary, and according to FDR speech writer Robert E. Sherwood was "particularly valuable as a contact man between the White House and Capitol Hill", until his death on 13 December 1943, in Washington, D.C.[2] McIntyre was succeeded by William D. Hassett, whom FDR named to fill the vacant post of Secretary to the president on February 19, 1944.
