Out Of This World is an American fantasy sitcom about a teenage girl who is half alien, which gives her unique supernatural powers. It first aired in syndication from September 17, 1987 and ended on May 25, 1991.

During its first season, the series was originally part of NBC's Prime Time Begins at 7:30 campaign, in which the network's owned-and-operated stations would run first-run sitcoms in the 7:30-8 pm time slot to counterprogram competing stations' game shows, sitcom reruns and other offerings. Out of This World was rotated with the original series Marblehead Manor and She's the Sheriff, a syndicated revival of the 1983 sitcom We Got It Made, and a television adaptation of the play You Can't Take It With You. NBC ended the experiment after the 1987-88 season due to the low ratings put up by three of the series, with Out of This World being one of the two that was renewed. After its first season the series was largely moved to weekend time slots, where it remained until its cancellation following the fourth season.

Mostra o dia-a-dia de Evie Garland, uma bela garota que tem um pequeno segredo: é metade-humana, metade-alienígena! Infelizmente, quando Evie descobriu sua verdadeira origem, seu pai não pode ajudá-la, pois estava há anos luz de distância, mas se prontificou a se comunicar com ela sempre que necessário através de um cubo mágico. Evie tem a habilidade de parar o tempo. Para isso, basta unir os seus dois dedos indicadores. Para que tudo volte ao normal, basta uma batida de palmas e, como num passe de mágica, ninguém percebe o que acontece.
