Finance Minister Paschal Donohoe is among a number of high-profile members of Na Fianna who have called for an immediate solution to the MetroLink row engulfing the GAA club.
The minister has called on transport authorities to respect the "vital role" clubs like Na Fianna play in their communities.
New GAA president John Horan is also a member. He has credited the club with igniting a flame and sparking his interest in Gaelic games.
Dublin All-Ireland winner Jonny Cooper is a club member who has been outspoken on the issue.
He has said the club is at the heart of the local community. He says the plans will have a negative impact on the area and the thousands of people who engage with it.
Architect and star of RTÉ's 'Room to Improve' Dermot Bannon has also backed local residents opposing the MetroLink plan. He lives in Glasnevin, his children attend local schools and are club members.
He said he would take part in any protest against the National Transport Authority's plans.
A proposal to use the grounds of Dublin's Na Fianna GAA Club as a construction site for the MetroLink rail service could be dangerous for children using a number of adjacent schools, according to the chairman for the Oireachtas Committee on Transport, Tourism and Sport.
