He was born 17 November 1897 in Knockaderry, County Limerick, one of two sons and a daughter of David O'Brien, a creamery manager, and Kathleen O'Brien (née Casey). He was educated at Ahalin national school and then at the Redemptorist College at Mount St Alphonsus, Limerick city, but was prevented from going to university by bouts of ill health.{{cite web|url=https://www.dib.ie/biography/o-briain-donnchadh-a6276|title=Ó Briain, Donnchadh|last=Rouse|first=Paul|work=Dictionary of Irish Biography|access-date=9 October 2022}}

On leaving school he worked in the creamery managed by his father for a number of years. By 1917, he had become involved in the independence movement as a member of Sinn Féin and later, of the West Limerick brigade of the Irish Republican Army. He was involved in the republican courts in Limerick and took the anti-treaty side in the Irish Civil War.

He was deeply involved in the Conradh na Gaeilge, which he also joined in 1917, having been influenced by Fr Tomás de Bhál. In 1920 Ó Briain was appointed Conradh na Gaeilge organiser for County Limerick, and from 1925 he served in that role for all of Munster province, founding numerous branches of the league. From 1928 to 1932 he served as general secretary of the Conradh na Gaeilge and also intermittently edited Fáinne an Lae.

A founder member of Fianna Fáil in 1926, he stood unsuccessfully in Limerick at the 1932 general election. He served as a Fianna Fáil Teachta Dála (TD) for the Limerick and from 1948 for Limerick West constituencies until 1969 when he retired from politics. He served in the governments of Éamon de Valera and Seán Lemass as Government Chief Whip.
