The West Lancashire derby (sometimes also known as the M55 derby) is a local rivalry in English football between Lancashire clubs Blackpool and Preston North End. The derby has taken place across all four tiers of English football, but not the top flight since the formation of the Premier League. Blackpool were promoted to the Premier League in 2010; Preston North End have yet to reach it. They did not meet in the League between the 2009–10 and 2020–21 seasons, but did so again in the 2021–22 EFL Championship campaign following Blackpool's promotion from the third tier.

The first West Lancashire derby took place on 23 November 1901 at Blackpool's Bloomfield Road. In front of a crowd of 6,000, Preston won 4–1. There have been 97 meetings between the two clubs in all competitions, with North End winning 47 to Blackpool's 32. The remaining 19 matches have been draws.

Background The derby is also known as the M55 derby because the town of Blackpool and city of Preston are at either end of the M55 motorway. The clubs' stadiums – Bloomfield Road and Deepdale, respectively – are seventeen miles apart. In the 2003 The Football Fans Census, fans of both clubs listed the derby as being the main derby, with both sets of fans agreeing that the other club is their main rival. Based on the survey, it was one of only 44 such rivalries in England.

Preston player Tom Finney, who played for the Lilywhites from 1946 to 1960, said: "We always saw Blackpool as our main rivals and we had some great matches against them. But there was none of the current nastiness from some fans." While Blackpool player Jimmy Armfield, who played for the Seasiders from 1954 to 1971, said: "The rivalry is mainly between the fans. It started with arguments over whether Stanley Matthews was better than Tom Finney in the '50s."

Ahead of the first derby of the 2008–09 season at Bloomfield Road on 15 November 2008, which Preston won 3–1, Blackpool chairman Karl Oyston said: "As chairman I get excited. It's difficult not to. I feel like telling the manager to feed the players on raw meat all week. I absolutely understand the rivalry, I am probably the person with the fiercest tribal views you can get. It's not to be under-estimated how strongly I feel about this game."

Preston fans refer to Blackpool and their fans as Donkey Lashers, in reference to the walking of donkeys along Blackpool beach. Likewise, Blackpool fans refer to Preston and their fans as Nobbers using an amendment of the word North from Preston North End, which is changed to Nob and sometimes Knob. Gary Peters, who was Preston manager from 1994 to 1998, took the rivalry so seriously that he would not use the word "Blackpool" in public, always referring to the club as "that lot with the tower".

In 2008, journalist Andy Mitten's book, Mad for It: From Blackpool to Barcelona: Football's Greatest Rivalries, included the derby as one of a number of "classic football derby matches".

Matches Matches between the two clubs have at times had significant consequences. For example, on 30 April 1904, Blackpool visited Deepdale for the final game of the season, and the home side's single-goal victory gave them the Division Two championship, edging out Woolwich Arsenal.

In 1912–13, Preston won the Division Two championship (and fellow Lancastrians Burnley were also promoted) while Blackpool finished bottom of the table. The Seasiders, however, were successful in their re-application to the League.

On 4 May 1921, Blackpool played a benefit match against Preston, with the proceeds going to the widow of Seasiders defender Horace Fairhurst, who died in February after suffering on-field head injury, and to the children of his partner at full-back, Bert Tulloch, whose wife had died the same weekend as Fairhurst.

It was until November 1925, at the sixth attempt, that Blackpool recorded their first home success against Preston. A brace by Bert Fishwick, together with a goal by Billy Meredith, gave the Seasiders a 3–1 victory.

Between 1946 and 1961, the derby took place in the top flight of English football for all but two seasons, with both clubs playing in the First Division. In the 1947–48 season both clubs were joint-favourites to win the FA Cup; however, Preston lost 4–1 to Manchester United in the quarter-finals while Blackpool made it to the final, in which they lost 4–2 to Manchester United.

On 1 May 1948, at Deepdale, Blackpool inflicted what still remains Preston's record loss in the Football League: 7–0. Jimmy McIntosh scored five goals and Alex Munro and Walter Rickett scored one apiece. The 1950s saw eighteen matches between the two clubs in the top flight in English football.

A record attendance at Bloomfield Road was set for the 9 October 1954 meeting of the two clubs. 36,204 witnessed a 2–1 victory for the visitors.

On 29 October 1955, in a 6–2 victory for Preston North End, George Farm became one of the few goalkeepers to score a goal. He injured a shoulder and replaced Jackie Mudie at centre-forward, where he proceeded to open the scoring with his head.

Blackpool ruined Preston North End's Christmas of 1958 with a festive double in the space of twenty-four hours. The Seasiders inflicted a 4–2 Christmas Day defeat on their neighbours at Bloomfield Road. When the two sides met again, on Boxing Day at Deepdale, the visitors were 3–0 victors.

During the first half of a friendly between the two clubs on 15 August 1966 came the news that Alan Ball had been transferred to Everton for a fee of £112,000. Ball was left on the bench, alongside Emlyn Hughes. Blackpool won this match, plus the two other meetings played inside seven days.

One of the most significant West Lancashire derbies took place on 13 April 1970, at Deepdale. Blackpool won the Second Division match 3–0, a result which saw them promoted back to the First Division, which was then the top flight, while the result later assisted in Preston's being relegated to the Third Division for the first time in the club's history. Blackpool striker Fred Pickering scored a hat-trick in front of a crowd of over 34,000 – over 15,000 of whom travelled from Blackpool, with another 3,000 Tangerines fans locked outside the stadium. Jimmy Armfield later said of that night: "The real rivalry started that night. It was such a significant result for both teams. Many [Blackpool fans] walked back to Blackpool and our bus passed them on the way home, dancing and singing by the road." Blackpool's joy was short-lived, however, as they spent just one season in the First Division before being relegated the next year.

In the 1972–73 season, Alan Ainscow scored his only hat-trick when Blackpool won 3–0 at Deepdale on 9 December 1972.

Alan Suddick scored his 100th League goal, a penalty, in Blackpool's 3–0 victory at Bloomfield Road on 23 March 1974. It was the last West Lancashire derby to take place at Bloomfield Road for fourteen years.

The two clubs met at Deepdale in the Anglo-Scottish Cup on 4 August 1979. With Preston leading 3–1 in the final minute, Blackpool goalkeeper Tom McAlister saved Ricky Thomson's penalty, tipping the ball onto the bar. It bounced down over the line, but by then the referee Ashley had blown his whistle to signal the end of the game. The goal did not count, but the spectators went home in the belief that the scoreline was 3–2. The official explained to Thomson and McAlister that the moment the ball had stopped travelling forwards the game was over and ruled it had ended the moment McAlister touched the ball. They met on two other occasions in the same competition: on 2 August 1978 at Deepdale (Preston won 4–2) and on 5 August 1980 at Bloomfield Road (Blackpool won 1–0).

In the Football League Group Cup at Deepdale on 15 August 1981, Preston won 2–1.

In the Lancashire Manx Cup, the two clubs met on several occasions. Firstly, on 17 August 1982, Blackpool won 2–1 at Bloomfield Road. 364 days later, the fixture was repeated, this time with the visitors winning 3–2. Two years later, on 3 August 1985, Blackpool won 2–1 at Deepdale. They did not meet again until 9 August 1988, when the teams drew 1–1 at Bloomfield Road. The following season, on 8 August 1989, Blackpool won 2–0 at home in the final meeting of the two clubs in the competition.

With both clubs languishing in the lower tiers of the Football League, some consolation came for Preston in the 1992–93 season, when they won 3–2 at Bloomfield Road, with Tony Ellis scoring a hat-trick.

On 17 April 1999, Brett Ormerod scored an injury-time winner for Blackpool at Deepdale.

The following campaign, after Preston's 3–0 Division Two victory over Blackpool at Deepdale on 18 December 1999, Nigel Worthington resigned as Blackpool manager.

The 1999–2000 season was also significant for Preston, who were then under the management of David Moyes. Their draw at Bloomfield Road in April 2000 assisted in their promotion from Division Two to the second tier of English football for the first time in twenty years. Later that month, Preston were crowned champions, while by the end of the season Blackpool were relegated to Division Three, the bottom division of the Football League, leaving two divisions between the clubs. The two clubs did not play each other for another seven years, during which time Preston finished fourth in their first season in Division One and reached the play-offs, losing out on promotion to the Premier League to Bolton Wanderers in the final. Two further play-off appearances followed, in 2004–05, when they again reached the final, and the following season, when they reached the semi-finals. Meanwhile, Blackpool languished in the bottom two divisions, before finally winning promotion back to the second tier (the Championship) in the 2006–07 season.

The two teams competed in the second tier between 2006–07 and 2009–10, at which point Blackpool won promotion to the Premier League for the first time and a return the top flight for the first time in 39 years. Blackpool survived in the Premier League for one season, but Preston were also relegated from the second tier to League One.

Four years later, at the end of the 2014–15 campaign, Blackpool dropped to the third tier for the first time since 2006–07. Preston, meanwhile, ended a run of nine consecutive unsuccessful appearances in the play-offs and returned to the second tier after four seasons away.

The 2020–21 season saw Blackpool promoted to the Championship. In October 2021 they won 2-0 at home, while Preston won the return game 1-0, while celebrating what would have been the 100th birthday of Tom Finney, who is considered to be Preston's greatest player.Match Report: PNE 1 Blackpool 0

Crossing the divide At least 53 individuals have represented both Blackpool and Preston North End at some point in their careers. 28 of these moved directly between the two clubs. One such example is Tony Ellis, who had two spells with Preston, in 1987–1989 and 1992–1994, and was Player of the Year in his final two seasons with the Lilywhites. During his second spell at the club, he scored a hat-trick for Preston at Bloomfield Road in a 3–2 Preston victory. However, after a much-publicised fall out with Preston manager John Beck over a new contract and his role within the club, Ellis signed for Blackpool for £165,000.
