The former defender played 333 times for the Reds from 1957 to 1969, helping them to two league titles and the FA Cup in 1965.
A statement on the official site reads:
"The Liverpool born defender was a model of consistency at left-back under Bill Shankly and a testament to his popularity was evident as 40,000 supporters were at Anfield for his testimonial in April 1970.
"The thoughts of everyone at Liverpool FC are with Gerry’s family and friends at this time."
