The football rivalry between Millwall and West Ham United is one of the longest-standing and most intense in English football. Originating in the late 19th century as a derby between rival shipbuilding and dockworking communities in East and South East London, the clubs were originally founded as Millwall Rovers (later Millwall Athletic) in 1885 on the Isle of Dogs, in the East End of London, and Thames Ironworks in 1895 in Canning Town in East London, then part of Essex. The match was historically known as the Dockers Derby, as both sets of supporters were predominantly dockworkers at shipyards on the River Thames. A central element of terrace tradition among West Ham supporters holds that Millwall dockers acted as strike-breakers during historic industrial disputes, a narrative that deeply intensified hostility between the two fanbases alongside competition for river trade.

In 1904, West Ham moved to the Boleyn Ground, more often referred to as Upton Park, which was in Essex until a London boundary change in 1965. In 1910, Millwall moved across the River Thames to New Cross in South East London and the teams were no longer East London neighbours. Both sides have relocated since, but remain just under four miles apart; Millwall moved to The Den in Bermondsey in 1993 and West Ham to the London Stadium in Stratford in 2016.

Millwall and West Ham have played each other 100 times competitively: Millwall have won 38, West Ham 34 and 28 have ended in a draw. Before the First World War, the teams met 60 times in just 16 years, mostly in the Southern and Western Football Leagues. They have played a total of 40 times in league and cup competitions since 1916. The teams have usually competed in different divisions, spending only 13 seasons in the same tier of the Football League. Even so, the derbies have retained their passion and both sets of supporters still consider the other club their main rival. As of the 2026–27 season, Millwall and West Ham both play in the Championship.

The rivalry between the teams is deeply embedded in British football hooliganism lore and culture, and has been depicted in books and films that focus specifically on the animosity between the clubs' two hooligan firms, the Inter City Firm or the Mile End Boys and the Millwall Bushwackers. Violence has occurred sporadically between the fans, resulting in the death of a Millwall supporter in 1976, and the murder of a West Ham fan in 1986. Most recently in the 2009 Upton Park riot, widespread disorder between supporters in and around West Ham's Upton Park ground led to numerous injuries and a Millwall fan being stabbed before the match began. In the last game between the sides in the 2026–27 season, the Metropolitan Police deployed 400 officers and implemented London-wide operations, including a large dispersal order across South London, to ensure the game was trouble-free.

History of the rivalry

Founding of the clubs: 1885–98

Millwall Rovers Football Club was formed in 1885 by tinsmiths at JT Morton's canned food factory on the Isle of Dogs in the East End of London.Lindsay, p.8 Ten years later, Thames Ironworks Football Club was formed by Dave Taylor, a foreman at Thames Ironworks and Shipbuilding Company, London's last major shipbuilding firm. Arnold Hills, the company owner, decided to form a football team to improve the morale of his workforce. The two clubs were situated less than three miles () apart.

The earliest meetings between the clubs were reserve games: the first ended in a 6–0 home win for Millwall Athletic ReservesMillwall Rovers were renamed Millwall Athletic in 1889. on 14 December 1895 over a newly formed Thames Ironworks side.Lindsay, p. 9 On 23 September 1897, the two sides played a first-team friendly match at Millwall's Athletic Grounds, Millwall Athletic won 2–0 in front of a crowd of 1,200 spectators.Powles, p. 53Lindsay, p. 372

Sixty meetings in sixteen years: 1899–1915 On 9 December 1899 the two teams met for their first competitive fixture – a Fifth Round qualifying match in the FA Cup. Millwall Athletic won 2–1 at Thames Ironworks' Memorial Grounds; their goal scorers were Hugh Goldie and Bert Banks. Millwall reached the 1899–1900 semi-final and lost 3–0 to Southampton, but gained the nickname The Lions from a newspaper headline heralding them as "The Lions of the South" for their cup exploits.Lindsay, p. 13 The teams' second competitive meeting was a Southern League match that spanned two centuries. A fixture at the Memorial Grounds on 23 December 1899 was abandoned after 69 minutes owing to smog, with Millwall leading 2–0. Instead of replaying the game, the remaining 21 minutes were completed after the return fixture four months later, on 28 April 1900. After Ironworks won 1–0, the players took a short rest and played the rest of the abandoned game. With no further score, Millwall won the game 2–0.Lindsay and Tarrant, p. 262

Thames Ironworks was disbanded in June 1900 owing to disputes over the running of the club. The following month it was relaunched as West Ham United. The club's nickname is The Hammers, owing to their Ironworks origins. In the 1901–02 and 1902–03 seasons, Millwall and West Ham competed in the Southern League, London League, Western League and Southern Professional Charity Cup. The two sides met seven times in each of these seasons, the highest number of meetings in a season between the clubs.Lindsay and Tarrant, p. 268 During this period Millwall were unbeaten in 12 consecutive games against West Ham, with nine wins and three draws over two years. This included a 7–1 win in a Southern Professional Charity Cup semi-final on 2 April 1903, the largest winning margin between the teams. Ben Hulse scored four of the goals at the Memorial Grounds.Lindsay and Tarrant, p. 166 The run was finally broken on 1 September 1904, in a 3–0 victory at West Ham's first ever game at Upton Park, with two goals from Billy Bridgeman and one by Jack Flynn. Upton Park was in Essex until 1965, and technically West Ham was not a London team again until an act of Parliament changed the boundary lines of London in 1965 and the Borough of Newham was formed.

On 17 September 1906, in a Western League game, Millwall player Alf Dean was hurled against a metal advertising board by West Ham's Len Jarvis. Others were stretchered off following heavy tackles. The East Ham Echo reported: "From the very first kick of the ball it was seen likely to be some trouble, but the storm burst when Dean and Jarvis came into collision (Millwall had two players sent off during the match). This aroused considerable excitement among the spectators. The crowds on the bank having caught the fever, free fights were plentiful."Dunning, p. 68 In 1910 Millwall decided to drop Athletic from their name and move out of East London. With limited expansion space on the Isle of Dogs, the club wanted to boost support and attendances. It moved four miles to The Den, in New Cross, South London.Lindsay, pp. 16–17 The last East London derby between the teams was at Millwall's North Greenwich ground on 24 September 1910; West Ham won 2–0 with goals from Danny Shea and Fred Blackburn.Lindsay and Tarrant, p. 284 Four months later, Millwall travelled to Upton Park as a team from South East London for the first time. The game ended in a 2–2 draw. On 9 March 1912, 28,400 supporters saw West Ham's first visit to The Den. The Lions won the game 5–1, with their Welsh international striker Wally Davis scoring a hat-trick.

Two World Wars and joining the Football League: 1915–45 A number of friendlies and non-competitive derbies took place during the First and Second World Wars. In total, 33 matches were played between the teams in Wartime Leagues.Lindsay, pp. 316–317 They both fielded severely depleted sides of juniors, reserves and non-professionals, playing 14 games in the London Combination between 1915 and 1919. West Ham won nine, Millwall three and two were drawn.Lindsay and Tarrant, pp. 294–300 After the First World War, the Football League was reintroduced in England by The Football Association and West Ham joined the Second Division for the 1919–20 season. Millwall joined the inaugural Third Division in the 1920–21 season, in the Football League expansion of 44 clubs to 66.Lindsay, p. 17

There is a tradition that antagonisms were deepened during the General Strike of 1926, or during a trade dispute a generation earlier; when a Millwall leaning workforce - typically said to be one of the dockyards - undermined working-class solidarity by becoming 'scab labour', either not going out on strike, or prematurely abandoning the strike. Some versions of the story cast the West Ham leaning workforces as the strike-breakers. This tradition has not been substantiated, there were no rival docks by 1926, the city's docks having been brought together under the management of the Port of London Authority in 1909. The dockyards on either side of the river held firm in the General Strike; with only seven out of two thousand workers at the Surrey Docks turning up for work on the strike's first day.

Between 1919 and 1929 the clubs played each other 11 times in the London Professional Footballers' Association Charity Fund and the London Challenge Cup, with West Ham winning five games, Millwall winning three, and three drawn. On 15 February 1930, West Ham won the Fifth Round FA Cup game 4–1 at Upton Park; Vic Watson scored two goals, and Viv Gibbins and Tommy Yews one each. Harold Wadsworth replied for the Lions.Lindsay and Tarrant, p. 322 The teams met for the first time in the Football League in the 1932–33 season, after West Ham were relegated from the First Division.Lindsay and Tarrant, pp. 300–322 On 17 September 1932, West Ham beat Millwall 3–0 at Upton Park in the Second Division, two goals being scored by Vic Watson and one by Jackie Morton.

On 27 December 1938, 42,200 spectators at Upton Park saw a Second Division game between the sides end 0–0. As of , this remains the record attendance for the fixture. Between 1939 and 1946 the two clubs played non-competitive fixtures in the League South (A) Division, South Regional League, London League, Football League South and the Football League War Cup.Lindsay and Tarrant, pp. 342–354 They played 19 games against each other during the Second World War: Millwall won 3, West Ham 12 and 4 were drawn. The Den was severely damaged by a German bomb in 1943, and for a brief time Millwall were invited by their neighbours Charlton Athletic, Crystal Palace and West Ham to play their games at The Valley, Selhurst Park and Upton Park. To offset the shortage of professional players during the Second World War, a guest player system was introduced. Players such as Sailor Brown, Louis Cardwell and Jimmy Jinks played for both clubs during this period. West Ham lost 2–1 to Chelsea at White Hart Lane in the 1944–45 War Time Cup semi-final, with two Millwall guest-players in their team – both of whom went on to play for Millwall in the South Final, which they lost to Chelsea 2–0.Lindsay and Tarrant, p. 235
