The central defender won the FA Cup and the UEFA Cup as part of Sir Bobby Robson’s highly-successful Ipswich side of the 1970s and early 1980s.
Beattie also won nine caps for England and was named PFA Young Player of the Year in 1973/74, as he became the first ever winner of the award.
“We are devastated to hear the news of the passing of Town legend Kevin Beattie at the age of 64,” Ipswich tweeted from their official account.
“The thoughts of everybody at #itfc are with Kevin’s family & friends at this very difficult time.
“The Beat. Thank you.”
