Munster Rugby is one of the professional provincial rugby teams from the island of Ireland. They compete in the United Rugby Championship and the European Rugby Champions Cup. The team represents the IRFU's Munster Branch, which is responsible for rugby union throughout the Irish province of Munster. The team motto is "To the brave and faithful, nothing is impossible." This is derived from the motto of the MacCarthy clan – "Forti et Fideli nihil difficile". Their main home ground is Thomond Park, Limerick, though some games are played at Musgrave Park, Cork.

The European Rugby Champions Cup is an annual rugby union tournament organised by European Professional Club Rugby (EPCR). It is the top-tier competition for clubs who compete in a predominantly European league. Clubs qualify for the Champions Cup via their final positions in their respective national/regional leagues or via winning the second-tier Challenge Cup; those that do not qualify are instead eligible to compete in the second-tier Challenge Cup.
