In the 1890s, he qualified as a solicitor and took up practice in Kanturk.
He was first elected as the All-for-Ireland League MP for the North Cork constituency at the 4 November 1913 by-election, which was held due to the death of the incumbent All-for-Ireland MP, Patrick Guiney, who was his eldest brother.
Like all All-for-Ireland League MPs, Guiney did not contest the 1918 general election as it had become evident that constitutional political concepts for attaining independent All-Ireland self-government were being displaced by Sinn Féin.
He died at his home at Egmont Place, Kanturk, County Cork, on 29 June 1931.
He was the father of David Guiney, an Irish Olympic athlete, sports journalist and historian.
