Former GAA director general Paraic Duffy has been appointed to the board of Sport Ireland.
Duffy spent a decade with the association up until 2018 and held a minor role with Sport Ireland in relation to facilities prior to joining the board.
Three other members have been added.
Michelle Tanner, head of sport and recreation in Trinity College, former Irish Olympian and now Bord Bia management member Deirdre Ryan and former Camogie Association president Miriam O'Callaghan have also joined.
The new appointments follow on from an application and shortlisting process run by the Public Appointments Service earlier this year.
Minister for Tourism, Culture, Arts, Gaeltacht, Sport and Media, Catherine Martin said: "I am delighted to appoint these four new members to the Board of Sport Ireland.
"They have all demonstrated that they possess skills and expertise which will greatly benefit the work of Sport Ireland in supporting and developing Irish Sport. I wish them well in their roles."
