The Big Moment is an American television game show that aired on ABC in 1999 and was hosted by Whose Line Is It Anyway? alumnus Brad Sherwood. John Cramer served as announcer. The show was based on a Japanese show of the same concept, Happy Family Planning.

The show's premise centered on one member of a family who was given one week to practice a certain task before the episode's taping. A video camera was provided to record the rehearsal process at home. At the end of the week, the contestant came to the studio to perform the task. The contestant was given only one attempt; if successful, he/she won a pre-selected prize package worth $25,000. If unsuccessful, he/she received a $2,000 consolation prize. Two contestants appeared each episode.

Some of the stunts presented:

⁕Memorizing pi to the 100th decimal

⁕Playing Beethoven's Für Elise on a piano, without missing a note

⁕Answering ten questions on the film Ghost

⁕Riding around three cones on a unicycle and returning to a starting line

⁕Pulling a tablecloth out from a fully set table without any items hitting the floor or glasses being knocked over
