The radio station has announced some shake-ups to its schedule.
Jenny Greene is leaving RTÉ 2FM's Drive Time to host a new show for the radio station.
Titled The Greene Room, the show will air from Sunday to Thursday from 10pm to 12am.
According to RTÉ, the programme will feature exclusive interviews and a mix of Irish music - including indie and alternative music - from Monday to Thursday.
Meanwhile, Sunday's episode is being described as "a chill-out show".
"Some personal news to share, today was my last day presenting Drive Time on RTÉ 2FM," Greene said in a statement.
"I’ve been incredibly lucky to present on daytime radio for the last seven years.
"Radio became a lifeline for us all over the last two years. At a time when we were all feeling very disconnected from friends and family, being able to connect with people and provide some light relief during a very dark time has been both an honour and a privilege.
"I joined 2FM in 2007 as a specialist music DJ and I have been given the opportunity to return to my first love and passion, which has always been music.
"The Electric Disco will continue as normal every Saturday and I’m really excited to be given this new and exciting opportunity to showcase many different genres of music that I love."
Jenny Greene's official replacement on Drive Time will be announced in the coming weeks, with Laura Fox to cover the slot in the meantime.
Meanwhile, Fox will also become the new voice of Saturday and Sunday mornings on 2FM from 9am with a new show titled Laura Fox at the Weekend.
On Saturdays, listeners will have the chance to win big with competitions as Fox chats with some of Ireland's biggest names in "music, fashion, beauty and beyond".
Then on Sundays, listeners can enjoy The Sunday Service when Aifric O'Connell will update Fox and the nation on all the best celebrity stories of the week gone by.
"Stations like 2FM must continue to evolve with audience needs," Head of 2FM and Radio Strategy Dan Healy said.
"We see an enormous opportunity for the station as more audiences listen to audio outside what was traditionally regarded as peak time radio."
