Mr O’Driscoll served as a member of An Garda Síochána for 41 years, including as the Assistant Commissioner for Special Crime Operations from 2016 until his retirement in 2022.
In that role he led garda efforts against the Kinahan cartel and other organised crime groups in Ireland.
In his tribute, the Taoiseach offered his condolences to Mr O’Driscoll’s wife Muriel and three children Michelle, Laura and Seán.
“John was a distinguished member of An Garda Síochána who served the force with such integrity,” he said.
“He was a very respected and admired member of the garda family and a true leader. I know the entire garda family will be mourning his loss today.
“I wish to extend my sympathies to John’s family and all his former colleagues.”
Commissioner Harris said Mr O’Driscoll was “an outstanding member of An Garda Síochána”.
“Throughout his 41 years of stellar service, John worked tirelessly to protect the most vulnerable in society and was a great advocate for the power of sport, particularly boxing, in helping and supporting children from deprived areas.
“In recent years, he was to the forefront in garda successes against organised crime. This work helped save lives and protect communities from the scourge of drugs.
“At this very difficult time, my thoughts and the thoughts of the entire garda organisation are with John’s wife Muriel and his children, Michelle, Laura and Seán. May he rest in peace.”
Ms McEntee said she was “shocked and saddened” to hear of Mr O’Driscoll’s death.
“John retired from An Garda Síochána in June 2022 after 41 years, the last six of which he spent as the Assistant Commissioner with responsibility for Special Crime Operations,” she said.
“He served the State with integrity and distinction over the course of his 41-year career in policing.
“He was a man who manifested integrity and decency, completely dedicated to public service and to serving the State to the very best of his considerable ability.
“Throughout his career he mentored scores of gardaí, built strong teams, and played a leading role in devising and implementing An Garda Siochana’s partnership with international law enforcement in tackling the scourge of organised crime groups.”
Mr O’Driscoll was due to publish his memoir, On Duty: Reflections on a Life in the Guards, at the end of October.
