Malahide R.F.C. was founded in 1922 and its initial patron was Lord Talbot of Malahide. In those years Malahide R.F.C. fielded two senior teams, playing in Leinster Branch IRFU, League and Cup competitions. Matches were played in Malahide Castle grounds, on the site where Malahide Cricket Club presently reside. Many players lived outside the village and travelled from Rush, Skerries and Dublin to play for Malahide R.F.C. At the end of each season an Honour Cap was awarded to the outstanding players for that season. The award took the form of a velvet cap, black in colour and rimmed with gold tassels with the relevant year embroidered on the front of the cap.

On the 27th September 1944, an Extraordinary General Meeting was held in the pavilion. It was presided over by Dr. H. Micheal and in attendance were eleven gloomy members. Shortage of members, local support was waning and World War II was taking its toll on membership, the last pass was taken and the ball grounded. The decision was taken to disband the club.

Those twenty-two glorious years had become part of the heritage of Malahide and many of the personalities associated with the early club still had connections with Malahide. So it was that some of these men held a re-union in The Grove Hotel, Malahide, Some ‘younger’ people also attended. As a result of a meeting (minutes below), Malahide R.F.C. was reformed in 1978.

Two pitches were rented in Malahide Castle grounds, now under the control of Fingal County Council as Lord Talbot had bequeathed the Castle and demesne to the Irish Government. In 1989 the club purchased their own land on the Back Road, opposite Malahide Castle. In March 1992 the clubhouse and pitch were officially opened.

Currently Malahide R.F.C. field two senior teams in various Leinster Branch IRFU competitions up to Leinster League Division 3 and Metropolitan J1. At youth level teams are fielded at Under 14 and 17 in Dublin Metropolitan Leagues and mini level teams are fielded at, Under 8, 9, 10 and 12, also competing in Dublin Metropolitan competitions.
