Supernanny is an American reality television program about parents struggling with aspects of raising their children (e.g. their children's behavior, mealtime, potty training, etc.). The show, featuring professional nanny Jo Frost, is an adaptation of the British series of the same name (also featuring Jo Frost). Frost devotes each episode to helping a family where the parents are struggling with their child-rearing. Through instruction and observation, she shows the parents alternative ways to discipline their children and regain order in their households. Frost is a proponent of the "naughty chair" theory of discipline and is strictly opposed to physical punishment. It aired on ABC from January 17, 2005, to March 18, 2011. A spin-off of the show was produced and was titled America's Supernanny.

On March 27, 2019, it was announced that Supernanny would return for a 20-episode season that premiered on January 1, 2020, on Lifetime with Frost as host again. The first 10 episodes from the season also began airing in the UK on July 20, 2020, on E4. The remaining set of episodes started airing on March 5, 2021.
