Breeda Moynihan-Cronin (née Moynihan), former Labour Party politician who serves as a Teachta Dála (TD) for the Kerry South constituency from 1992 to 2007, is born in Cork, County Cork, on March 31, 1953.

Although born in Cork, Moynihan-Cronin is a native of Killarney, County Kerry. She is educated at St. Brigid’s Secondary School in Killarney, Dominican College Sion Hill in Dublin, and Skerry’s College, Cork. Her father, Michael Moynihan, is a TD for Kerry South from 1981 to 1987 and from 1989 to 1992. She works as a bank official before becoming involved in politics in 1991 when she is elected to Kerry County Council. She is first elected to Dáil Éireann at the 1992 Irish general election as a Labour Party TD for Kerry South, succeeding her father. She is re-elected at every election until 2007.

Moynihan-Cronin holds a number of front bench positions in the Labour Party, including, Spokesperson on Justice, Equality and Law Reform (1997–98), Social, Community and Family Affairs(1998–99), Tourism and Recreation (1999–2002), Social, Community and Family Affairs (2002–03), and Equality and Law Reform (2003–07). She is a former chairperson of the Labour Party.

On October 11, 2005, Moynihan-Cronin announces that she will not stand for re-election at the forthcoming general election due to ill-health. Her decision to retire presents considerable difficulties for the Labour Party to retain her seat, as the party performed poorly at the 2004 Kerry County Council election, failing to elect any councillors within the county. However, on October 28, 2006, she announces that she will stand in the forthcoming general election, having overcome her health difficulties. However, she fails to retain her seat.

In June 2011, Moynihan-Cronin returns to politics when she is co-opted onto Kerry County Council to represent the Killarney area, filling the seat left vacant when Marie Moloney is elected to the 24th Seanad. In 2013, she stands down from the council and is replaced by Sean Counihan.
