The parade for Féile Peil na nÓg 2011 saw almost 100 busloads of players transported into the city centre from early evening.
The route of the parade, which kicked off at the Mardyke at 7.30pm, ending up in Grand Parade, was lined with GAA supporters and families of those taking part in the matches.
Each team was easily distinguishable by the large team flag they carried at the front of their ranks.
More than 101 Irish teams were joined by 80 visiting teams from London, Hertfordshire, Yorkshire, Warwickshire, Lancashire, Scotland, New York and Philadelphia.
The competition will continue until tomorrow when the 10 finals will be played in Páirc Uí Caoimh and Páirc Uí Rinn. This is the first time the Féile will be held in Cork since 1986, having also been held on Leeside in 1985.
