John Joe Nevin has lost his bantamweight final at the London Olympics but has won a silver medal.
The Co Westmeath boxer was defeated by Luke Campbell from Britain by 14 points to 11. Up to 6,000 people gathered in Mullingar to watch the fight on a big screen.
A homecoming parade will take place in the town on Monday for the Olympian.
Elsewhere, Rob Heffernan has finished fourth in the Men's 50km Walk event. Colin Griffin and Brendan Boyce also competed in the event.
Arthur Lanigan-O'Keeffe has become the first Irishman to compete in the Modern Penthalon, which combines fencing, swimming, riding, running and shooting.
No official team homecoming
There will be no official event in Dublin to mark the homecoming of the Irish Olympic team on Monday.
Many members of Team Ireland are due to return to Dublin airport at lunchtime on Monday and efforts had been made to organise an event in the city centre.
However, the Olympic Council of Ireland informed Dublin City Council that most of the athletes were anxious to get home as soon as they could.
Athletes may take part in a press conference at Dublin Airport on their return, and then travel home individually. Efforts are underway to have an event later - possibly at Farmleigh House in the Phoenix Park.
President Higgins has already invited the team to a reception at Áras an Uachtaráin.
