Presidential elections were held in the United States on November 3, 2020. The Democratic ticket of former vice president Joe Biden and California junior senator Kamala Harris defeated the incumbent Republican president Donald Trump and vice president Mike Pence. The election saw the highest voter turnout by percentage since 1900. Biden received more than 81 million votes, the most votes ever cast for a presidential candidate in U.S. history.

In a competitive primary that featured the most candidates for any political party in the modern era of American politics, Biden secured the Democratic presidential nomination. Biden's running mate, Harris, became the first African American, first Asian American, and third female vice presidential nominee on a major party ticket. Trump secured re-nomination, getting a total of 2,549 delegates, one of the most in presidential primary history, in the Republican primaries. Jo Jorgensen secured the Libertarian presidential nomination with Spike Cohen as her running mate, and Howie Hawkins secured the Green presidential nomination with Angela Nicole Walker as his running mate.

The central issues of the election included the public health and economic impacts of the COVID-19 pandemic; civil unrest in reaction to the police murder of George Floyd, the Supreme Court following the death of Ruth Bader Ginsburg and confirmation of Amy Coney Barrett, and the future of the Affordable Care Act. Due to the ongoing pandemic, a record number of ballots were cast early and by mail.
