The Voting Rights Act of 1965 (42 U.S.C. §§ 1973–1973aa-6) is a landmark piece of national legislation in the United States that outlawed discriminatory voting practices that had been responsible for the widespread disenfranchisement of African Americans in the U.S.

Echoing the language of the 15th Amendment, the Act prohibits states from imposing any "voting qualification or prerequisite to voting, or standard, practice, or procedure ... to deny or abridge the right of any citizen of the United States to vote on account of race or color." Specifically, Congress intended the Act to outlaw the practice of requiring otherwise qualified voters to pass literacy tests in order to register to vote, a principal means by which Southern states had prevented African-Americans from exercising the franchise. The Act was signed into law by President Lyndon B. Johnson, a Democrat, who had earlier signed the landmark Civil Rights Act of 1964 into law.

The Act established extensive federal oversight of elections administration, providing that states with a history of discriminatory voting practices (so-called "covered jurisdictions") could not implement any change affecting voting without first obtaining the approval of the Department of Justice, a process known as preclearance. These enforcement provisions applied to states and political subdivisions (mostly in the South) that had used a "device" to limit voting and in which less than 50 percent of the population was registered to vote in 1964. The Act has been renewed and amended by Congress four times, the most recent being a 25-year extension signed into law by President George W. Bush in 2006.

Suffrage, political franchise, or simply franchise, distinct from other rights to vote, is the right to vote gained through the democratic process. In English, suffrage and its synonyms are sometimes also used to mean the right to run for office (to be a candidate), but there are no established qualifying terms to distinguish between these different meanings of the term(s). The right to run for office is sometimes called (candidate) eligibility, and the combination of both rights is sometimes called full suffrage. In many other languages, the right to vote is called the active right to vote and the right to be voted for (to run for office) is called the passive right to vote. In English, these are sometimes called active suffrage and passive suffrage.

Suffrage is often conceived in terms of elections for representatives; however, suffrage applies equally to initiative and referendum. Suffrage describes not only the legal right to vote, but also the practical question of whether a question will be put to a vote. The utility of suffrage is reduced when important questions are decided unilaterally by elected or unelected representatives.
