The Amazing Race 16 is the sixteenth 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 five continents and nine countries and traveled over 40,000 miles (64,000 km). Starting in Los Angeles, racers traveled through Chile, Argentina, Germany, France, the Seychelles, Malaysia, Singapore, and China before finishing in San Francisco. This season also saw the return of the Intersection. The season premiered on CBS on Sunday, February 14, 2010, and the finale aired on May 9, 2010. In Canada, the show premiered on the A-Channel instead of CTV due to the 2010 Winter Olympics, but it returned to CTV after the Winter Olympics concluded.

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.
