Wigan Athletic Football Club is a professional association football club based in Wigan, Greater Manchester, England. The team competes in the EFL League One, the third level of the English football league system.

Founded in 1932, they have played at the 25,138-seat Brick Community Stadium since 1999, before which they played at Springfield Park. Their colours are blue and white stripes, although all-blue shirts have been common throughout the club's history. The club regards Bolton Wanderers as its primary derby rival.

Wigan competed in the Cheshire County League for the first nine seasons of the club's existence, winning three league titles before being placed in the Lancashire Combination in 1947. It spent 14 years in the Lancashire Combination and secured four league titles during this time. It spent 1961 to 1968 back in the Cheshire County League, picking up another league title in 1964–65. Invited to become a founder member of the Northern Premier League in 1968, the club won two league titles and also reached the FA Trophy final in 1973. Wigan was elected to the Football League in 1978 and was promoted out of the Fourth Division in 1981–82. The club won the Associate Members' Cup in 1985, but was relegated back into the fourth tier in 1993. It won the Third Division title in 1996–97, the Football League Trophy in 1999 and the Second Division in 2002–03, before securing promotion out of the Championship in 2004–05.

Wigan lost in the League Cup final in 2006 and won the FA Cup in 2013, beating Manchester City in the final. However, the club was relegated later that year, bringing its eight-season stay in the Premier League to an end. The FA Cup success did, though, gain it a place in the UEFA Europa League group stages the following season. Relegated from the Championship in 2015, the club won the League One title in 2015–16 and repeated this feat in 2017–18 after another relegation. On 1 July 2020, less than a month after a change of ownership, it was placed into administration and was relegated from the Championship due to the subsequent points deduction. After narrowly avoiding relegation to League Two in 2020–21 under new ownership, Wigan won the League One title for a fourth time in 2021–22, but a year later were again relegated from the Championship following two further points deductions. Additional deductions of points were made in May 2023, meaning the club started the 2023–24 League One season with minus eight points.

Wigan Athletic was formed in 1932, following the winding-up of Wigan Borough the year before. The establishment of Wigan Athletic was the sixth attempt to create a stable football club in the town following the demise of Wigan A.F.C., Wigan County, Wigan United, Wigan Town and Wigan Borough. The town's die-hard football enthusiasts planned the rebirth of a town team, and a public meeting was held at the Queen's Hall presided over by the then Mayor of Wigan, Councillor W.A. Hipwood, and Callum Roper, who called on the town to keep up its reputation for producing fine sportsmen by keeping intact an Association Football team as well as the Rugby League team. A committee was elected and a new club was formed, Wigan Athletic. Springfield Park, the former home of Wigan Borough, was purchased by the club for £2,850 from the owners of the Woodhouse Lane dog track. Despite their initial application being turned down, Wigan Athletic were elected into the Cheshire County League following the resignation of Manchester Central. The club had also made the first of many attempts to be admitted into the Football League, but failed to receive a single vote. On 27 August 1932, Wigan Athletic played their first-ever league game against Port Vale Reserves. The team played in red and white shirts with black shorts.

Wigan Athletic won its first honours in the 1933–34 season, finishing top of the Cheshire League, despite being based in neighbouring Lancashire. In the following season the club won a second league championship and also entered the FA Cup for the first time, defeating Carlisle United 6–1 in the first round – a cup record for the biggest victory by a non-League club over a League club. In the 1935–36 season, the club won its third consecutive Cheshire League title and the Lancashire Junior Cup.

After the Second World War, Wigan Athletic adopted their present-day blue and white colours. The club struggled to assemble a competitive side and finished bottom of the league in 1946–47 season. Despite their pre-war success, the club failed to gain re-election and was replaced by Winsford United. The club joined the Lancashire Combination, winning the league in their first season. In 1950, Wigan Athletic came close to election to The Football League, narrowly losing out to Scunthorpe United and Shrewsbury Town. The club would frequently apply for election to the Football League over the next 28 years before finally being accepted.

In the 1953–54 season, Wigan played an FA Cup match against Hereford United in front of a crowd of 27,526 – a club record and also a record attendance for a match between two non-League teams at a non-League ground. In the next round of the cup, Wigan Athletic was drawn against First Division side Newcastle United. Wigan Athletic held their top-flight opponents to a 2–2 draw at St James' Park, but went on to lose the replay 3–2. In 1961, the club moved back to the Cheshire League.
