The Amazing Race 25 is the twenty-fifth season of the American reality competition show The Amazing Race. Hosted by Phil Keoghan, it featured eleven teams of two, each with a pre-existing relationship, competing in a race around the world in order to win US$1,000,000. This season visited four continents and ten countries and traveled over 26,000 miles (42,000 km). Starting in New York City, racers traveled through the U.S. Virgin Islands, England, Scotland, Denmark, Sweden, Morocco, Italy, Malta, Singapore, and the Philippines before finishing in Greater Los Angeles. New twists introduced in this season include a public start; the Save, which was awarded to the winners of the first leg and would save them from elimination once; an Express Pass hidden on the racecourse; the Blind Detour, where teams learned about the task that they chose after arriving at its location; and four teams racing in the final leg. The season premiered on CBS on September 26, 2014, with the season finale airing on December 19, 2014.

The Amazing Race is an American reality competition show in which teams of two race around the world. Each season is split into legs, with each leg requiring teams to deduce clues, navigate themselves in foreign areas, interact with locals, perform physical and mental challenges, and travel by airplane, boat, taxi, and other public transportation options on a limited budget provided by the show. Teams are progressively eliminated at the end of most legs, while the first team to arrive at the end of the final leg wins the grand prize of US$1 million. As the original version of the Amazing Race franchise, the CBS program has been running since September 5, 2001. Numerous international versions have been developed following the same core structure, while the American version is also broadcast to several other countries.
