The silent majority is an unspecified large group of people in a country or group who do not express their opinions publicly. The term was popularized by U.S. President Richard Nixon in a televised address on November 3, 1969, in which he said, "And so tonight—to you, the great silent majority of my fellow Americans—I ask for your support." In this usage it referred to those Americans who did not join in the large demonstrations against the Vietnam War at the time, who did not join in the counterculture, and who did not participate in public discourse. Nixon, along with many others, saw this group of Middle Americans as being overshadowed in the media by the more vocal minority.

Preceding Nixon by half a century, it was employed in 1919 by Calvin Coolidge's campaign for the 1920 presidential nomination. Before that, the phrase was used in the 19th century as a euphemism referring to all the people who have died, and others have used it before and after Nixon to refer to groups of voters in various nations of the world.
