The amendment that allowed women to vote in the United States is the Nineteenth Amendment to the U.S. Constitution.

Quick Scoop

  • The Nineteenth Amendment prohibits denying the right to vote on the basis of sex.
  • It was passed by Congress on June 4, 1919, and ratified on August 18, 1920.
  • Its ratification meant women nationwide could no longer be barred from voting simply because they were women.

A tiny bit of story

For decades before 1920, women organized, marched, lobbied, and were even jailed to push for voting rights, turning what many saw as a “radical” idea into constitutional law. When Tennessee became the crucial 36th state to ratify the amendment in August 1920, it crossed the threshold needed to change the Constitution and finally secured women’s suffrage across the country.

In short: when people ask “which amendment allowed women to vote,” the answer is the Nineteenth Amendment —the one that permanently bars states and the federal government from denying the vote “on account of sex.”

TL;DR: The Nineteenth Amendment (ratified in 1920) is the amendment that allowed women to vote in the United States.
