Niall Collins (born 30 March 1973) is an Irish Fianna Fáil politician who has served as a Minister for State since July 2020.

In February 2023, political news website The Ditch published a story claiming that Collins had misled Limerick County Council about his place of residence in a 2001 planning application.
