Smith has opted to stand down after 20 years in the role following the fantastic high of leading Eastern Region IRL to the UEFA Regions Cup title last summer.
The Dubliner previously led the Irish representatives to the UEFA Regions Cup Final in 2011 when they were beaten by hosts Braga from Portugal.
Smith, 60, also managed the Republic of Ireland at the World U20 Championships Finals in the UAE in 2003. He also worked with Brian Kerr in a scouting and analysis role at the successful 1998 U18 UEFA Championships Finals in Cyprus.
His time with the junior international side including winning the Quadrangular tournament four times and securing runners-up six times. Smith and his squad also won the Davie Pocock Cup twice against the Netherlands.
Smith’s 35 games as manager in the UEFA Regions Cup saw his Irish representatives qualify for final tournaments five times. His Irish side’s last ten competitive games were all victories.
“I feel the time is right for me to step down from the role having reached the pinnacle by winning the UEFA Regions Cup in 2015,” said Smith.
“I have enjoyed the job immensely and wise to extend my sincere appreciation and gratitude to the secretary Dennis Cruise, the committee, council members and all past Presidents for the help and cooperation in making my job that much easier over the years.
“I would also like to place on record my thanks to all my own backroom staff and all the players who have played under me as a manager over the years. I have made great friends and will be eternally grateful to the FAI for the opportunity to manage such a great group of people.
“It is my intention to stay involved in football in the future but for now I’ll be recharging the batteries. So for the next weeks and months I’ll be at games and trying to enjoy them in a different way. We got out on a high and that’s all you can ask for.”
