United 2026, also known as the North American 2026 bid, was a successful joint bid led by the United States Soccer Federation, together with the Canadian Soccer Association and the Mexican Football Federation, to host the 2026 FIFA World Cup in Canada, Mexico, and the United States of America.

On June 13, 2018, at the 68th FIFA Congress in Moscow, Russia, the United bid was selected by 134 votes to Morocco's 65. Upon this selection, Canada will become the fifth country to host both the men's and women's World Cup, joining Sweden, the United States, Germany, and France. Mexico will become the first country to host three men's World Cups, and the United States will become the first country to host both the men's and women's World Cup twice each. This will be the first World Cup to be hosted in three countries, as well as the first since 2002 and the second overall to be held in multiple countries.

In July 2012, Canadian Soccer Association president Victor Montagliani confirmed plans for a Canadian bid, saying: "We have verbally told FIFA that when the bid process begins for the next available World Cup, which would be the 2026 World Cup, that the CSA will be one of the countries putting in a formal proposal". At the time the bid was announced, Canada had hosted the men's 1987 Under-16 World Championship and the U-20 World Cups for both men and women; the country has since hosted the 2014 FIFA U-20 Women's World Cup and the FIFA Women's World Cup in 2015. In October 2013, Montagliani confirmed Canada's intention to bid for the 2026 tournament and the Canadian Soccer Association reiterated this in January 2014.

In September 2012, Mexican Football Federation (FMF) President Justino Compeán confirmed plans for a Mexican bid. In October 2013, Liga MX President said that Mexico was interested in joining forces with the U.S. to co-host a bid for the 2026 World Cup. On December 9, 2014, FMF confirmed that it was bidding for the 2026 World Cup.

On May 13, 2016, at the FIFA Congress in Mexico City, USSF board member John Motta told ESPN "whatever happens, we will bid for the 2026 World Cup -- either jointly (with Mexico or Canada) or we will do it alone." The United States hosted the 1994 FIFA World Cup and unsuccessfully bid for the 2022 World Cup, which was won by Qatar in 2010. On April 18, 2015, Brazilian legend Pelé stated that the United States should host the 2026 World Cup.
