The History of Dundalk Football Club (1903–1965) briefly describes the introduction of association football to the town of Dundalk, Ireland in the pre-World War I period, then subsequently covers the period from the formation of the Dundalk G.N.R. Association Club in September 1903 to the takeover of the club as a public limited company in January 1966. This page also includes short articles about events and people that were an integral part of that period of the club's history.

Football's origins in the town (1889–1914) Contemporary records of organised association football in the Dundalk area between the late 1880s (when the game was introduced), and the end of the World War I, are incomplete. The earliest reference to a Dundalk team playing in competition appears in the Belfast Newsletter of 2 October 1889, which stated that "Dundalk" had been drawn to play Newry Wanderers in the First Round of the Irish Football Association Irish Junior Cup – the third year of the competition. This side was a team from the Educational Institution (now Dundalk Grammar School). The school had adopted the game under its principal Thomas A. Finch, who had played while a student at Trinity College Dublin. Older references to "Dundalk F.C." and "Dundalk Football Club" actually refer to the modern-day Dundalk Rugby Club, formed in 1877.

In 1892, a new team called 'Dundalk' was formed. The Dundalk Democrat reported on a match that had occurred on Saturday 3 December 1892, which was the fifth encounter between Dundalk and the Institution 2nd XI, after four previous draws. This club established itself as the premier club in the town between about 1895 and 1904. They were runners-up to Bohemians in the 1896–97 Leinster Senior Cup Final, and were invited to enter the Leinster Senior League for the 1900–01 season in September 1900. They adopted the name "Dundalk Rovers" for the step up, but they did not survive the season, being requested to resign from the League "owing to their inability to fulfil their engagements". The club continued to compete in the junior cup competitions, however, reaching the Leinster Junior Cup Final in 1903, where they lost to St. Patrick's of Inchicore.

Before the 1904–05 season commenced, the clubs of the town amalgamated under the 'Dundalk Association Football Club' banner in order to give the town a better chance at success in competition. The representatives of the Nomads club insisted that the 'Rovers' moniker be dropped to show that the new club was to represent the whole town. The amalgamated club reached the Leinster Junior Cup Final that season, being defeated by Shamrock Rovers. The following season it led the foundation of the Dundalk and District League (DDL) alongside Drogheda, St. Nicholas's, St Mary's College, Carrickmacross, and the Great Northern Railway. To "save ambiguity" they became known as Rovers again and formalised the name change the following year.

St Mary's College won the DDL in its first season, with British Army sides winning it for the following three seasons. The League appears to have been inactive for the seasons 1909–10 to 1912–13, at a time when Gaelic football had become the dominant sport in the county (with Louth qualifying for three All-Ireland Finals in those years). Rovers were replaced by St Nicholas's as Dundalk's representatives in the Irish and Leinster Junior Cup competitions in those seasons. The DDL was reformed in 1913–14, and Rovers returned to the league and to contest the Junior Cups. But that was their last season of competition before World War I broke out. After they failed to fulfil a 1914–15 Irish Junior Cup tie with Dundalk G.N.R. in November 1914, Rovers disappeared from competition until 1924, by which time 'the Railwaymen' had become the preeminent football club in the area.
