During the 1960s
Mick Higgins was the coach of Longford when it won the National Football League (1966) and its first (and at the time of his death only)
Leinster Senior Football Championship (SFC) (1968). He also led them to an
O'Byrne Cup title in 1965. Jackie Devine set up two goals for Longford in the last six minutes of the 1968 Leinster SFC final to beat
Laois by 3-9 to 1-4, where
Seán Donnelly and Jim Hannify were the scorers. It was their only Leinster SFC title, and it came two years after a great victory over
Galway on a scoreline of nine points to eight in the National League final. Longford also won the O'Byrne Cup in 1965, 2000 & 2020. When Longford lost a replayed Leinster SFC semi-final in 1970 it was the county's fourth semi-final in six years and 8th time reaching the semi-final stage. After 1970, Longford reached the Leinster SFC semi-final twice, in 1988 and 2018 (losing to Dublin on both occasions).
Brendan Hackett managed the team between 1987 and 1990 in his first managerial role at inter-county level. Longford made the 1988 Leinster SFC semi-finals and also two quarter-finals of the
National Football League. 2001 saw Longford surrender the O'Byrne Cup in the opening round. The league saw Longford win four from the first five games, but defeats to
Monaghan and
Kildare in the final round meant there was no promotion. The championship began with victory over Louth in Navan to set up an SFC quarter-final against Dublin. Longford ultimately won well in that game, at
Croke Park. 2001 also saw the introduction of the back door, or qualifiers. Longford's first second chance outing was away to Wicklow, though Longford lost by a scoreline of 1-14 to 0-11. Denis Connerton was appointed manager in 2001 and managed the team until 2004 when he was replaced by
Luke Dempsey. In 2010, 2011 and 2012, Damien Sheridan won the
All-Ireland Kick Fada Championship. In October 2013,
Jack Sheedy was confirmed as the team's new manager. The footballers had mixed fortunes in 2014. The Leinster SFC campaign finally yielded a win over Offaly for new manager Jack Sheedy on a scoreline of 0-19 to 0-15, but a 1-13 to 1-15 defeat to Wexford followed in the quarter-final, in the sunshine of Pearse Park. The All-Ireland SFC qualifier draw paired Longford with
Derry, a high-scoring game which Longford won by two points. However, in the next round,
Tipperary inflicted a 17-point defeat on Longford to end the county's 2014 championship campaign. Denis Connerton replaced Sheedy as manager in 2015; it was Connerton's second spell in charge having previously managed the team during the 2002 and 2004 seasons. Former player
Padraic Davis took over as manager in 2018. Davis was given a two-year extension in 2020 until the end of 2022. But he quit at the end of the 2021 season after losing to Meath by 22 points, referring to his family, his property market job and the difficulties of managing at that level. Laois native
Billy O'Loughlin was appointed Longford manager in November 2021. He resigned at the end of the 2022 season, citing work commitments.
Paddy Christie won back-to-back O'Byrne Cup titles before stepping down as manager in 2024. Mayo's
2016 All-Ireland Under-21 Football Championship-winning manager
Mike Solan replaced him, arriving from
Sligo GAA club
Tourlestrane. ==Panel==
