All My Children (often shortened to AMC) is an American television soap opera that aired on ABC from January 5, 1970, to September 23, 2011, and on The Online Network (TOLN) from April 29 to September 2, 2013, via Hulu, Hulu Plus, and iTunes.

Created by Agnes Nixon, All My Children is set in Pine Valley, Pennsylvania, a fictional suburb of Philadelphia, which is modeled on the actual Philadelphia suburb of Penn Valley. The original series featured Susan Lucci as Erica Kane, one of daytime television's most popular characters. All My Children was the first new network daytime drama to debut in the 1970s. Originally owned by Creative Horizons, Inc., the company created by Nixon and her husband, Bob, the show was sold to ABC in January 1970. The series started with half-hour episodes before expanding to a full hour on April 25, 1977. The show had experimented with the full-hour format for one week starting on June 30, 1975, after which Ryan's Hope premiered.

From 1970 to 1990, All My Children was recorded at ABC's TV18 at 101 West 67th Street, now a 50-story apartment tower. From March 1990 to December 2009, it was taped at ABC's Studio TV23 at 320 West 66th Street in Manhattan, New York City, New York. In December 2009, taping moved from Manhattan to less costly Los Angeles, California, at Stages 1 and 2 of the Andrita Studios, from 2010 to 2011. Taping then moved to the Connecticut Film Center in Stamford, Connecticut. All My Children started taping in high definition on January 4, 2010, and began airing in high definition on February 3, 2010. All My Children became the third soap opera to be produced and broadcast in high definition.

At one point, the program's popularity positioned it as the most widely recorded television show in the United States. In the mid-1970s, its audience was estimated to be 30% male, which was unusual at the time. The show ranked first in the daytime Nielsen ratings in the 1978–79 season. Throughout most of the 1980s and into the early 1990s, All My Children was the number-two daytime soap opera on the air. However, like the rest of the soap operas in the United States, All My Children experienced unprecedented declines in its ratings during the 2000s.

On April 14, 2011, ABC announced that it was canceling All My Children after a run of 41 years. On July 7, 2011, ABC sold the licensing rights of All My Children to third-party production company Prospect Park with the show set to continue on the internet as a series of webisodes. The show taped its final scenes for ABC on August 30, 2011, and its final episode on the network aired on September 23, 2011, with a cliffhanger. Prospect Park had suspended its plan to revive the series on November 23, 2011, due to lack of funding and unsuccessful negotiation with the union organizations representing the actors and crews.

On January 7, 2013, Prospect Park officially brought back its project to restore All My Children as a web series. The show taped its first scenes for Prospect Park TOLN on February 18, 2013, and its first episode on the network aired on April 29, 2013. However, the new series faced several behind-the-scene obstacles throughout its run. On November 11, 2013, several All My Children cast members announced that Prospect Park had closed production and canceled the series again. The rights to the show went back to ABC in December 2016.
