Sir Charlie Mayfield will take over from Kingfisher boss Sir Ian Cheshire as chair of the British Retail Consortium when he steps down in September.
Before taking on the role of chair, Mr Mayfield will start his term of office as vice chair in May when Rob Templeman comes to the end of his term of office.
Mr Mayfield has been chairman of the John Lewis Partnership, which is a longstanding member of the BRC, since 2007.
Speaking about the role, Mr Mayfield said: "I am very much looking forward to working with Ian for the next six months and then chairing the BRC as we continue to modernise and campaign on behalf of the whole industry.
"Building on the great work the BRC has led over recent years, it is critical that we continue to have a strong and effective trade association to galvanise retail employers and attract the best new talent from across society into retail."
Director general of the BRC, Helen Dickinson, added: "We're extremely pleased that Charlie is to become our new chair. The experience and leadership he brings will be essential as we continue to represent retail at its best."
