The Irish Universities Rugby Union (IURU) organises four domestic 15 - a - side tournaments on an annual basis.
All four IURU competitions are all now competed for in a "Festival of Rugby" tournament which is held on one day and in one location over the October Bank Holiday weekend each year.
In 2015, 8 separate Universities from across the island of Ireland were represented by 25 teams and almost 550 players making the Festival of Rugby the largest gathering of the Third Level rugby community in Ireland.
The Festival provides a unique opportunity for the tertiary rugby sector to demonstrate to stakeholders the breadth, depth and vibrancy of rugby activity across the Universities of Ireland. Take a look back at the 2015 festival - click here.
The IURU also organises Student representative fixtures against other representative sides inside and outside Ireland.
In the past, the Combined Universities have played against full International touring sides, including the famous victory over the Springboks at Thomond Park in 1965.
In recent years, the Irish Universities have organised fixtures against other European Student representative sides.
2016 saw the revival of the third level international representative team in the guise of the Ireland Students.
Ireland's long and proud history of third level representative rugby has been hindered in recent years due to the pressures of the professional era and this year's fixture, organised by the IURU, was designed as a launch-pad for the reintroduction of regular internationals for Irish student teams.
