Dundalk F.C.

Dundalk Football Club (/dʌnˈdɔː(l)k/ dun-DAW(L)K) is a professional football club that competes in the League of Ireland First Division. It was founded in 1903 as Dundalk G.N.R., the works-team of the Great Northern Railway. It is based in Dundalk, County Louth and its home ground is Oriel Park. The club crest is three martlets on a shield, which was adopted from the town's coat of arms. The team's traditional kit colours are white shirts, black shorts, and white or black socks.

Dundalk were a junior club until they were invited to join the Leinster Senior League in 1922–23. After playing at that level for four seasons, they were elected to the League of Ireland for the 1926–27 season. Six seasons later, they became the first club from outside Dublin to win the league title. As of 2024, they have won 47 trophies at national level, including 14 League titles and 12 FAI Cups (with four League and Cup 'Doubles'). They are the only club to have won a league title or an FAI Cup in every decade since the 1930s.

They made their European debut in the 1963–64 European Cup and that season became the first Irish side to win an away match in Europe. Their best performance in the European Cup was in 1979–80, when they reached the last 16, and they reached the last 16 of the European Cup Winners' Cup in 1981–82. They are the only Irish club to have qualified more than once for the Europa League group stage and, in 2016–17, they became the first team from Ireland to both win points and win a match at that level of European competition. They remain the only Irish team to have won points in the Europa League group stage as of the 2024–25 European season.
