Walker managed the Ireland U18s during the early 1970s with a squad that included the likes of Liam Brady, Frank Stapleton and Don O'Riordan, competing in the 1973 UEFA Youth Championships Finals in Italy.
He was a well known figure in the League of Ireland for many years with St Patrick's Athletic, Longford Town, Home Farm and Shamrock Rovers, where he managed the reserves for a spell.
The Dubliner was instrumental in bringing Paul McGrath to St Pat's from Leinster Senior League outfit Dalkey United in 1981.
He passed away sadly at the weekend after a short illness. He was, beloved husband of the late Rose and loving father of Linda, Derek and Joan. He will be sadly missed by family and friends.
FAI CEO John Delaney said: "It was with great sadness that we learned of Charlie Walker's passing at the weekend. He was a great football man and I recall he managed St Patrick's Athletic in the 1980 FAI Cup Final against Waterford and also managed our underage teams with great pride. We will pay tribute to him in the Ireland-Austria match programme. Our thoughts are with his family at this time."
Republic of Ireland U21 head coach Noel King said: "I played under Charlie for many years with Home Farm. He's a great loss as a person first and foremost but he was well known throughout the game as a great character with an eye for a player. We all remember well how he brought Paul McGrath to St Pat's. He was also interested in all aspects of the game and his interest in coaching had an influence in my own move in that direction."
