The American Broadcasting Company (ABC) is an American commercial broadcast television and radio network that serves as the flagship property of the Disney Entertainment division of the Walt Disney Company. ABC is headquartered on Riverside Drive in Burbank, California, directly across the street from Walt Disney Studios and adjacent to the Team Disney – Roy E. Disney Animation Building. The network maintains secondary offices at 7 Hudson Square in New York City's Lower Manhattan neighborhood, which houses its broadcast center and the headquarters of its news division, ABC News. Until early 2025, the network's East Coast operations were based at 77 West 66th Street on the Upper West Side of Manhattan. Since 2007, when ABC Radio (also known as Cumulus Media Networks) was sold to Citadel Broadcasting, ABC has reduced its broadcasting operations almost exclusively to television. The youngest of the "Big Three" American television networks, the network is sometimes referred to as the Alphabet Network, as its initialism also represents the first three letters of the English alphabet in order.

ABC launched as a radio network in 1943, as the successor to the NBC Blue Network, which had been purchased by Edward J. Noble. It extended its operations to television in 1948, following in the footsteps of established broadcast networks CBS and NBC, as well as the lesser-known DuMont. In the mid-1950s, ABC merged with United Paramount Theatres (UPT), a chain of movie theaters that formerly operated as a subsidiary of Paramount Pictures. Leonard Goldenson, who had been the head of UPT, made the then-new television network profitable by helping to develop and green-light many successful television series. In the 1980s, after purchasing an 80 percent interest in cable sports channel ESPN, the network's corporate parent, American Broadcasting Companies, Inc., merged with Capital Cities Communications, owner of several television and radio stations and print publications, to form Capital Cities/ABC Inc., which in turn merged into Disney in 1996.

ABC has eight owned-and-operated and more than 230 affiliated television stations throughout the United States and its territories. Some ABC-affiliated stations can also be seen in Canada via pay-television providers, and certain other affiliates can also be received over-the-air in areas near the Canada–United States border, although most of its prime time programming is subject to simultaneous substitution regulations for pay television providers imposed by the Canadian Radio-television and Telecommunications Commission (CRTC) to protect rights held by domestically based networks. ABC News provides news and feature content for select radio stations owned by Cumulus Media, as these stations were former ABC Radio properties.

In 1927, NBC operated a radio network called the NBC Blue Network. It became an independent radio (and eventually television) network known as the American Broadcasting Company (ABC) in 1943. ABC later joined United Paramount Theatres forming American Broadcasting-Paramount Theatres (later American Broadcasting Companies, Inc.). After its venture into radio and television throughout the 1960s and 1970s and the purchase of ESPN in 1982, the company was acquired and merged with Capital Cities, forming Capital Cities/ABC in 1986. The company was sold to the Walt Disney Company in 1996.

The ABC television network provides an average of 89 hours of network programming each week. It also offers 22 hours of prime-time programming to affiliated stations from 8:00 p.m. to 11:00 p.m. Monday through Saturday (Eastern and Pacific Time) and 7:00 p.m. to 11:00 p.m. on Sundays.

Daytime programming is also provided from 11:00 a.m. to 3:00 p.m. Eastern and Pacific weekdays (subtract 1 hour for all other time zones) (with a one-hour break at 12:00 p.m. Eastern/Pacific for stations to air newscasts, locally produced programming or syndicated programs) featuring the talk-lifestyle shows The View and GMA: The Third Hour, and the soap opera General Hospital. In addition, ABC News programming includes Good Morning America from 7:00 a.m. to 9:00 a.m. weekdays and Saturdays (along with one-hour Sunday editions), nightly editions of ABC World News Tonight (whose weekend editions are occasionally subject to abbreviation or preemption due to sports telecasts overrunning into the program's timeslot), the Sunday political talk show This Week, early morning news programs World News Now and America This Morning and the late-night newsmagazine Nightline. Late nights featured the weeknight talk show Jimmy Kimmel Live! until its suspension in September 2025.

The network's three-hour Weekend morning children's programming timeslot is programmed by syndication distributor Litton Entertainment, which produces Litton's Weekend Adventure under an arrangement in which the programming block is syndicated exclusively to ABC owned-and-operated and affiliated stations, rather than being leased out directly by the network to Litton.

ABC's daytime schedule features the talk show The View, news show GMA: The Third Hour, and the soap opera General Hospital. Originally premiering in 1963, General Hospital is ABC's longest-running entertainment program. In addition to the long-running All My Children (1970–2011) and One Life to Live (1968–2012), notable past soap operas seen on the daytime lineup include Ryan's Hope, Dark Shadows, Loving, The City and Port Charles. ABC also aired the last nine years of the Procter & Gamble-produced soap The Edge of Night, following its cancellation by CBS in 1975. ABC Daytime has also aired several game shows, including The Dating Game, The Newlywed Game, Let's Make a Deal, Password, Split Second, The $10,000/$20,000 Pyramid, Family Feud, The Better Sex, Trivia Trap, All-Star Blitz and Hot Streak.
