This includes all cup seasons from:

FA Cup since 2010/11

EFL Cup since 2011/12

Copa del Rey and DFB Pokal since 2005/06

Coupe de France since 1947/48

Coppa Italia since 2003/04

until 3rd of November 2023.

I could only go back as far as the Wikipedia Pages of the cup campaigns state the league tiers each club played in that very season. For some unknown but pleasant reason the Coupe de France is tracked very throughly, so we could go back extremely far there. We won’t see any Italian upsets in the further post because the Coppa Italia is constructed very elitist which barely allows any matchup of even 3rd division clubs with Serie A teams, let alone 4th or 5th division teams.

In the seasons considered as noted above there have been 17 occasions in which a team from the 1st tier was knocked out by a team from the 5th tier:

Season, Round Team won Result Team lost
49/50, 1 SC La Bastidienne Bordeaux 3-2 RC Lens
87/88, 1 US Endoume Catalans Marseille 2-1 after extra time AS Cannes
95/96, 1 CS Blénod 1-0 SC Bastia
98/99, 1 Jura-Sud Foot 8-7 after pens FC Toulouse
98/99, 2 US Saint-Georges-les-Ancizes 1-0 FC Sochaux
02/03, 1 SC Schiltigheim 3-1 ESTAC Troyes
05/06, 2 SR Colmar 1-0 after extra time AS Monaco
07/08, 2 US Jeanne d’Arc Carquefou 2-1 after extra time AS Nancy

16/17, 3 Lincoln City 1-0 Burnley
21/22, 1 ESA Linas-Montlhéry 2-0 SCO Angers

And 4 more occasions in which a team from the 6th division pulled off the unlikely:

Season, Round Team won Result Team lost
59/60, 2 AS Gardanne 3-2 FC Toulouse
81/82, 1 US Sanary 7-6 after pens Montpellier
18/19, 1 ES Viry-Châtillon 1-0 SCO Angers
22/23, 1 FCO Strasbourg Koenigshoffen 06 4-3 after pens Clermont Foot

The “Round” in the 1st column starts the count whenever the 1st division teams entered the competitions.

I actually also wrote down all times when a 4th division did it but I am not gonna spam you with that big list, but I would like to note a few interesting upsets. All teams from 4th division which knocked out at least two 1st division teams within one season:

Season, Round Team won Result Team lost
97/98, 2 FC Bourg-Péronnas 3-2 Montpellier
97/98, 2 FC Bourg-Péronnas 2.0 FC Metz
99/00, 4 Calais RUFC 2-1 RC Strasbourg
99/00, 5 Calais RUFC 3-1 after extra time Bordeaux
01/02, 1 FC Libourne-Saint-Seurin 2-0 Lille OSC
01/02, 2 FC Libourne-Saint-Seurin 2-1 after extra time FC Metz
03/04, 1 Aviron Bayonne 5-3 after pens EA Guingamp
03/04, 2 Aviron Bayonne 1-0 after extra time Bordeaux
05/06, 1 AS Lyon-Duchère 2-1 FC Toulouse
05/06, 2 AS Lyon-Duchère 5-4 after pens RC Strasbourg
06/07, 3 FC Montceau 5-4 after pens Bordeaux
06/07, 4 FC Montceau 1-0 RC Lens

12/13, 3 Bradford City 4-2 after pens Wigan Athletic
12/13, 4 Bradford City 3-2 after pens Arsenal
12/13, 5 Bradford City 4-3 on aggregate Aston Villa
13/14, 1 AS Cannes 1-0 after extra time AS Saint-Étienne
13/14, 3 AS Cannes 4-3 after pens Montpellier
19/20, 2 1. FC Saarbrücken 3-2 1. FC Köln
19/20, 4 1. FC Saarbrücken 7-6 after pens Fortuna Düsseldorf
19/20, 1 Colchester United 5-4 after pens Crystal Palace
19/20, 2 Colchester United 4-3 after pens Tottenham
20/21, 1 Rot-Weiss Essen 1-0 Arminia Bielefeld
20/21, 3 Rot-Weiss Essen 2-1 after extra time Bayer Leverkusen

Add to that the 5th division teams US Jeanne d’Arc Carquefou and SO Chambéry as seen in the first table. Bradford was the only team to knock out as many as 3 1st division teams. A special shout-out to Crawley Town who knocked out a 1st division team in the 1st cup round of 3 of the last 4 seasons (Norwich, Leeds, Fulham).

        When there is a 2 division gap, the amateur team automatically hosts.

        Ligue 1 teams join with the first game post winter break - meaning their first game after a 2 week break is on a terrible half frozen pitch.

        There also seems to be a favouring of smaller sides, commentators (games are on state tv) are extremely pro amateurs.

        Added to that, the French cup is the largest national cup in the world with a massive amount of amateur teams participating. There are some amateur clubs who have made it a speciality of theirs to be giant killers during the cup (Quevilly and Carquefou)

        If a team has to play the league + europe, the cup is the least of concern. Also there was the french cup AND league cup before, which we finally got rid of few years ago. Too many matches

      It’s because I was able to use the biggest time range for them by far. Not sure how the distribution would be if you would just consider 2010 until now where the data was available for all 5 leagues (or 4 without Italy).

      Not sure there’s a football (even sports in general?) competition with that many teams?

    Fucking Bradford, I remember that game. Literally had starting XI players and Gervinho (our starting no. 9 at the time) proceeds to have a masterclass in missing a tap-in.

    At least Swansea and Michu won a trophy.

    Spurs won the FA Cup in 1901 without even being in the football league. First and only non-league team to win it.

    In Italy there are multiple Coppa Italias: the big one for serie A and B, the coppa Italia serie C and lastly the coppa Italia serie D. There’s also a Coppa Italia primavera for the youth level.

    We got beat by Yeovil who were in the 8th tier (I think?) in 1949, we were arguably the biggest club in the country at that point too.

    Wasn’t Alcorcon in 4th division when they knocked Real Madrid out of Copa Del Rey in 2009?
