Live-In is an American sitcom created by Robert Sternin and Prudence Fraser that aired on CBS from March 20 to May 22, 1989. The series focuses on young Australian au pair Lisa Wells (Lisa Patrick) integrating into the home life of a New Jersey family and their teenage son Danny Mathews' (Chris Young) efforts to become her boyfriend. Nine episodes were filmed in Los Angeles, which CBS hoped would draw a younger audience to the network.

While premiering to decent ratings, subsequent episodes suffered from low viewership, and CBS canceled the mid-season replacement before the final episode aired. The show received highly negative reviews from television critics; some named it one of the worst series of 1989 and felt it did not live up to CBS' reputation for airing high-quality programming. They described the writing as childish and thought the content was unoriginal, but were mostly approving of Patrick's role.
