The 62-year-old Jamaican, who stood in a record 128 Tests, ended his 20-year career with the final Test between South Africa and Australia at Newlands in Cape Town.
“His endurance is testament to discipline and consistency – two characteristics to which all in cricket should aspire,” said Haroon Lorgat, the ICC’s chief executive.
“On behalf of the ICC, thank you for your great service to the game and we wish you well in the future.”
One of the game’s most respected umpires, Bucknor has also stood in 179 one-day internationals and will add to that tally when he officiates the two matches between West Indies and England at Kensington Oval in Barbados this weekend.
The experienced Bucknor has also stood in a record five consecutive World Cup finals since 1992, a standard that Lorgat contended would never be overhauled.
“His record of five consecutive ICC Cricket World Cup finals will not, be overtaken and he will retire as the umpire to have officiated in the most Test matches and the first to break the 100-Test mark.”
