ESPN on ABC (formerly known as ABC Sports) is the brand used for sports programming on the ABC television network. Officially the broadcast network retains its own sports division; however, for all practical purposes, ABC's sports division has been merged with ESPN, a sports cable network majority-owned by ABC's parent, The Walt Disney Company.

ABC broadcasts use ESPN's production and announcing staff, and incorporate elements such as ESPN-branded on-screen graphics, SportsCenter in-game updates, and the BottomLine ticker. The ABC logo is used for the digital on-screen graphic in the bottom right hand corner of the screen, and is also used for promotions so that viewers will know to tune into the broadcast network and not the ESPN cable channel.

Prior to September 2, 2006, the broadcast network's coverage carried the ABC Sports brand, although integration of ABC's sports division with ESPN had begun a decade earlier. The branding change was made to better orient ESPN viewers with the programming on ABC and provide consistent branding across ESPN's outlets (shortly thereafter, ESPN2's in-game graphics were likewise changed to refer simply to "ESPN"). Despite its name, ABC's sports coverage is supplemental to and not a simulcast of ESPN, although ESPN and ESPN2 will often carry ABC's regional broadcasts that otherwise wouldn't air in certain markets.
