Lost was a US reality television show screened in the USA in late 2001. It was a game show in a race format where teams raced around the world with little or no resources.

The premise was similar to The Amazing Race except the three two-member teams knew only the final destination (thousands of miles away) and were given only a backpack full of clothes and other essentials. The home-viewing audience knew that the starting point was central Mongolia but the teams did not. The finish line was the Statue of Liberty in New York City.

The show was produced by Conaco , a production company owned by Conan O'Brien. Al Trautwig, a sports broadcaster, narrated the show.

Only four episodes were screened after the show premiered to dismal ratings; NBC blamed the lackluster numbers on the show debuting just before the September 11, 2001 attacks. The winners were announced on the final episode. A few months later, a second set of episodes originally filmed for NBC were aired on the Travel Channel. It was revealed in the second set that there was more to the show than just getting to the destination. The contestants had to go back via an island, making the quest more arbitrary.
