20/20 (stylized as 20²⁰) is an American television newsmagazine that has been broadcast on ABC since June 6, 1978. Created by ABC News executive Roone Arledge, the program was designed similarly to CBS's 60 Minutes in that it features in-depth story packages, although it focuses more on human interest stories than international and political subjects. The program's name derives from the "20/20" measurement of visual acuity.

The two-hour-long program has been a staple on Friday evenings (currently airing at 9:00 p.m. Eastern Time Zone) for much of the time since it moved to that timeslot from Thursdays in September 1987, though special editions of the program occasionally air on other nights. For most of its history, it was led into by ABC's two-hour TGIF block of sitcoms.

Since the fall of 2018, it has shifted to a two-hour format highlighting true crime stories and celebrity scandals rather than the traditional investigative journalism associated with newsmagazines, following the same programming direction as same-night competitor Dateline NBC.
