Sinn Féin leader Mary Lou McDonald has made clear she will not be the party's presidential candidate if it decides to contest this autumn's election.
Ms McDonald said Sinn Féin had just commenced its considerations on how it would approach the election and has not yet made a decision on whether it will run its own candidate.
Amid speculation that left-leaning parties in the Dáil may seek to back an agreed independent candidate, Ms McDonald acknowledged that was an option Sinn Féin would consider.
President Michael D Higgins' second and final seven-year term in office ends on 11 November when the winner of the election will be inaugurated.
While an election to find his successor must take place within his final 60 days in office, the poll is expected to be held in late October.
Earlier this week, Taoiseach Micheál Martin ruled himself out as Fianna Fáil's candidate.
Ms McDonald was asked about her party's plans, and whether she might be a candidate, as she spoke to reporters at Stormont.
"On the presidential election, we've just commenced really our discussions around what we might do," she said.
"We're speaking with others, other parties, and there are options available to us - to run a Sinn Féin candidate, to back another - and we haven't concluded on that."
She pushed back on the suggestion that there had been speculation linking her to a presidential run.
"Just to say no, it won't be me," she added.
"I want Sinn Féin to be in government in Dublin. I still believe that we can achieve that, and I know that for progress to be made in so many areas, in housing and giving a chance for our younger people in particular, we need a change of government.
"And all of my energy and my effort is towards achieving that," Ms McDonald said.
The party has recently also rejected speculation linking Sinn Féin’s deputy leader Michelle O'Neill to a potential run in the presidential election.
In the 2018 election, Sinn Féin had a disappointing day, with candidate Liadh Ní Riada coming fourth in the contest, securing just over 6% of the first preference votes.
Fielding questions from reporters, Ms McDonald also declined to be drawn on mixed martial arts fighter Conor McGregor's declared intention to seek a candidacy.
"That's a matter for himself," she said.
Ms McDonald added: "I think it's going to be an important contest come the autumn time. The position of the first citizen of Uachtarán na hÉireann is a very, very important one, not just domestically, but also internationally. And I think there'll be considerable competition for the post.
"And Michael D's done a great job, I think we can all agree."
