The 88 members of An Garda Síochána who have died in the line of duty were remembered at a ceremony held at Dublin Castle.
Minister for Justice Charlie Flanagan addressed the annual Garda Memorial Day in the Dubhlinn Gardens.
Garda Adrian Donohoe and Garda Tony Golden, who lost their lives in Co Louth in recent years, were remembered during the ceremony.
Detective Garda Donohoe was shot dead during an armed robbery at a credit union in Bellurgan in January 2013, while Garda Golden was shot dead at Omeath in October 2015.
Mr Flanagan described both men as heroes who left behind them wives and children, families and friends.
The minister said that he recognised the impact of their deaths on gardaí working in the Louth division.
He also mentioned Garda Michael Clerkin, who was killed in the line of duty while following up on a plot to kidnap the minister's father, Oliver Flanagan, also a Fine Gael TD, in 1976.
