Saturday Night Football (currently branded as ABC Saturday Night Football presented by Capital One for sponsorship reasons) is an American weekly presentation of prime time broadcasts of National Collegiate Athletic Association (NCAA) Division I Football Bowl Subdivision (FBS) college football games that are produced by ESPN, and televised on ABC. Games are presented each Saturday evening starting at 7:30 p.m. Eastern Time/6:30 p.m. Central Time during the college football regular season, which has been the case since 2017 (some weeks until 2015 saw no game on ABC, due to Saturday evening Sprint Cup Series NASCAR coverage or to avoid competition with the World Series; ESPN would then carry that week's high-profile game instead, with ESPN2 carrying a secondary game usually seen on ESPN/ABC). Saturday Night Football began in 2006, as both ESPN and ABC are owned by The Walt Disney Company. It is typically ESPN's biggest game of the week, and in most cases (outside where other networks carry the game), the city and/or campus of that night's game will host College GameDay.

As of 2025^[update], the primary broadcast team for the majority of the games includes play-by-play announcer Chris Fowler and analyst Kirk Herbstreit, with Holly Rowe as sideline reporter. Kevin Negandhi and Booger McFarland host the halftime show, with Dan Orlovsky joining them for select weeks. Negandhi also provides in game updates throughout the game. Other ESPN broadcast teams may also occasionally appear for regional (and some national) telecasts.

Saturday Night Football premiered on September 2, 2006, with a game between the Notre Dame Fighting Irish and Georgia Tech Yellow Jackets. While ABC and ESPN have aired college football games on Saturday nights for decades, this program marks the first time that a collegiate sports broadcast has officially been part of any major broadcast television network's primetime schedule.

Twelve weeks of regular season games were televised during the three-month college football season in 2006, 2007 and from 2009 to 2011; the Dr. Pepper Big 12 Football Championship Game closing out each season until a conference realignment in which four university football programs left and two others joined the Big 12 Conference resulted in the Championship Game being discontinued after the 2010 event (the Big 12 Football Championship Game returned in 2017, however, it did not return to ABC until 2018, when the network aired the game in the afternoon instead of in primetime). With the college football season being extended by one week, ABC televised thirteen weeks of games in 2008, closing with the 2008 Big 12 Championship Game on December 6. With the loss of the Sprint Cup Series to NBC and NBCSN, Saturday Night Football expanded its seasonal game schedule full-time to 13 weeks beginning in 2015, starting with the Advocare Classic.

Games from the Atlantic Coast Conference, the Big 12 Conference, the old Big East Conference, the Big Ten Conference, the Pac-12 Conference, the now-defunct Western Athletic Conference and the American Athletic Conference have aired on Saturday Night Football, as well as non-conference games in which teams from these conferences were either playing at home or a neutral-site game to which ABC holds the television rights. All BCS/CFP and Power 5 conferences have appeared on Saturday Night Football, as the Southeastern Conference has had its teams featured in 23 non-conference games. Boise State, Utah State, BYU, Temple, UConn, UCF, Cincinnati, SMU, Tulsa, and Memphis are the only Group of 5 teams to be featured on Saturday Night Football to date, with the latter four teams being featured when they were members of the BCS-aligned Big East or American Athletic Conference.

In recent years, following the loss of some broadcast rights of the Pac-12 Conference to Fox Sports in 2012, the Pac-12's Saturday Night Football appearances have been limited, sometimes including home games against Notre Dame and games against the Southeastern Conference, as well as road games against conferences that still have broadcast rights with ABC.

Besides Pac-12 and Big Ten games, ABC makes most of its game broadcast selections or options twelve days prior to the game (with some being made six days beforehand). This allows ABC to 'flex' the most compelling game it has the rights to broadcast into the Saturday Night Football slot. As a result, the Saturday night game is usually ABC's "game of the week".

With ESPN's acquisition of its top football package beginning in 2024, Southeastern Conference home games began to be featured on Saturday Night Football on ABC for the first time that season. As with afternoon games, SEC home games on Saturday Night Football utilize the distinct SEC on ABC graphics and theme music.
