NFL’s Biggest Rivalries: The Complete Guide
Few things define an NFL fanbase quite like its rivalries. Division opponents who meet twice a year, conference foes who’ve collided in championship games, and old-guard matchups that trace back to the league’s earliest decades all combine to make rivalry week some of the most anticipated football on the calendar. This guide rounds up the NFL’s most significant rivalries, from century-old division battles to more recent playoff-fueled grudge matches.

The League’s Marquee Rivalries
A handful of NFL rivalries have earned standalone deep dives on GridironHoops, each with enough history and statistical texture to warrant a full breakdown on its own. Packers vs. Bears is the most-played rivalry in NFL history, dating back to 1921, and remains the standard-bearer for old-school divisional hatred. Chiefs vs. Bills has become the defining rivalry of the current era, built almost entirely on a string of instant-classic playoff games between Patrick Mahomes and Josh Allen. Cowboys vs. Eagles brings NFC East intensity to a fever pitch every season, with two of the league’s most passionate fanbases separated by less than a two-hour drive. Each of those matchups gets the full treatment elsewhere on the site — this guide focuses on the rest of the league’s essential rivalries.
Packers vs. Vikings: The Border Battle
Green Bay and Minnesota have squared off as division rivals since the Vikings joined the league in 1961, and the “Border Battle” nickname reflects the geographic proximity that’s fueled the series ever since. As of the 2026 season, the Packers hold a narrow all-time edge in the series, a margin that’s shifted several times across more than six decades of play — the Vikings won 22 of 32 meetings during a stretch from 1964 to 1979, while the Packers answered with a run of their own from 1979 to 1990. The two sides have met twice in the playoffs, splitting a pair of NFC Wild Card games in 2004 and 2012. With both franchises consistently competitive in the NFC North throughout the 2020s, the rivalry has stayed as relevant as ever.
Bears vs. Lions: The NFL’s Longest Unbroken Series
No two teams have played every single season of their existence against one another quite like the Bears and Lions, who’ve met annually since 1930, making it the longest continuously played series in NFL history. Chicago holds the all-time edge, a lead built up over nearly a century of football, though the Lions’ resurgence into an NFC contender over the past several seasons has made recent meetings considerably more competitive than the series’ historical average. The rivalry’s Thanksgiving Day tradition, with 18 meetings on the holiday dating back to 1934, remains one of its most enduring hallmarks.
Rams vs. 49ers: California’s NFC West Rivalry
The Rams and 49ers have been playing since 1950, and few rivalries illustrate how dramatically momentum can swing across football eras. The Rams won 10 straight meetings between 1974 and 1978, one of the longest streaks in the series’ history, before San Francisco flipped the script during the Bill Walsh and George Seifert dynasty years, reeling off a 17-game winning streak of its own between 1990 and 1998. That stretch pushed the 49ers into the all-time series lead, one they’ve largely maintained since, even as the Rams’ return to Los Angeles in 2016 and subsequent Super Bowl runs have reinjected fresh intensity into the matchup.
Broncos vs. Raiders: An AFL Original
Denver and Oakland/Las Vegas have been rivals since both were founding members of the American Football League in 1960, and the Raiders hold the all-time edge in a series that’s produced 130-plus meetings. The rivalry’s early decades were lopsided in the Raiders’ favor — Oakland won 17 straight meetings at one stretch from the 1960s into the 1970s — before John Elway-era Denver teams and later Peyton Manning-led squads evened things out considerably. The two teams have met twice in the playoffs, splitting those games, including a memorable 1977 AFC Championship win that sent the Broncos to their first Super Bowl.
Chiefs vs. Raiders: The AFC West’s Other Blood Feud
Kansas City and the Raiders franchise have been division rivals since the AFL days of the early 1960s, and the matchup carries a physical, old-school rivalry reputation that’s persisted across multiple decades and multiple Raiders relocations, from Oakland to Los Angeles and back to Oakland before the franchise’s most recent move to Las Vegas. The rivalry cooled somewhat during periods when one team struggled competitively, but the Chiefs’ sustained dominance of the AFC West through the Mahomes era has added a new layer to a series that once revolved primarily around the Raiders’ 1970s and ’80s success.
Cowboys vs. Commanders: An NFC East Original
Dallas and Washington have been divisional rivals since the Cowboys joined the league in 1960, and the matchup remains one of the NFC East’s foundational rivalries alongside Cowboys-Eagles and Giants-Eagles. The two franchises’ shared history includes some of the division’s most bitter moments, and while Washington’s competitive struggles across parts of the 2000s and 2010s dimmed the rivalry’s on-field intensity at times, the fanbase animosity has remained constant regardless of either team’s standings in a given season.
What Makes an NFL Rivalry Endure
The rivalries that last tend to share a few common traits: divisional proximity that guarantees two meetings every season, sustained periods where both teams are competitive at the same time, and at least one signature moment — a controversial finish, a championship-game meeting, or a multi-year win streak — that gets retold by each fanbase for decades afterward. That’s part of why rivalries like Packers-Bears and Bears-Lions, both dating back nearly a century, still carry weight even in seasons when one team is clearly down, while newer rivalries like Chiefs-Bills have managed to build serious intensity in a comparatively short window simply by delivering big games on the biggest stages.
The Bottom Line
The NFL’s rivalry landscape spans everything from century-old division series to fresher, playoff-forged grudge matches, and each carries its own distinct texture shaped by geography, history and the specific eras when both teams were good at the same time.
