The British Boxing Board of Control (BBBofC) has branded the decision to allow professional boxers to compete at Rio 2016 as "dangerous".
An International Boxing Association (AIBA) vote on Wednesday gave the green light for professionals to challenge for Olympic gold in Brazil, 84 of the 88 member federations giving the ruling their backing.
The change will see professionals given the chance to qualify for the Games at an event in Venezuela next month, with 26 places available.
However, the BBBofC has criticised the ruling and believes it could put amateur boxers - who normally compete in the Games - in danger.
"Following the announcement that AIBA are to permit professional boxers to compete in future Olympic Games, the British Boxing Board of Control confirm their objection to such a proposal," a statement read.
"It is the belief of the British Boxing Board of Control that such a move is against the spirit of the Olympics, disrespectful to the many GB Amateur boxers who, throughout the Olympic cycle compete around the world in qualifying tournaments and ultimately dangerous.
"It is the hope of the British Boxing Board of Control and many within the professional sport in Great Britain and throughout the world that AIBA reconsider such a move that is not beneficial to the sport as a whole."
