[citation needed] Blackrock College are the most successful school in the cup's history, having won 71 times, more than all other teams combined.

These are Blackrock, who have achieved this feat 26 times (1910, 1912, 1927, 1933, 1935–36, 1942–43, 1945, 1948, 1953–54, 1956–57, 1962, 1964, 1981–82, 1986–87, 1995, 2004, 2006, 2013–14, 2018), St Michaels twice (2012 & 2019), Newbridge (2020), Belvedere (2005), Terenure (1958) and Castleknock College (1920).

The 1977 Leinster Senior Schools Cup Final was played on Sunday 20 March 1977 and not the normal St Patrick's Day.

This decision was made to protect the Lansdowne Road pitch following poor weather prior to the Ireland v France Five Nations fixture on 19 March.

Only very few rugby playing secondary schools opted to join the "Free Education" scheme.

[citation needed] The most international players produced have come from Blackrock College, with players such as Hugo MacNeill, Brendan Mullin, Brian O'Driscoll, Victor Costello, Shane Byrne, Bob Casey, Leo Cullen, Luke Fitzgerald, Ian Madigan, Jordi Murphy, Garry Ringrose and Joey Carbery.

However it emerged afterwards that Clongowes fielded an illegible player and the Schools committee ordered a replay.

In September 2013, Beauchamps Solicitors became the title sponsor for the Leinster Schools Senior Cup.

Both publish previews of each year's competition and provide match reports for each game played.

[citation needed] The competition's final on St Patrick's Day was previously broadcast on TG4, however, this was discontinued in the early 2000s.

The Leinster Senior Cup was most prominent, however, with coverage from every game played at Donnybrook and every round of the competition.

It is named in memory of Vincent Murray, a teacher in Clongowes Wood college who trained the rugby team and died in December 1999.

[21] Gonzaga College, The King's Hospital[22] and St Gerard's School have won the trophy twice.
