Neville-Rolfe, who was made a dame in the Queen’s Birthday honours ‘ list in 2012, most recently held the role of executive director of corporate and legal affairs at Tesco.
She left Tesco in January this year, after 15 years with the retailer.
Neville-Rolfe was also named a Conservative life peer in August and is non-executive director at ITV and fund management firm Hermes Equity Ownership.
Prior to joining Tesco she was director of the deregulation unit for the Department for Business Innovation & Skills between 1995 and 1997, a member of John Major’s policy unit from 1992 to 1994 and also served in the Department for Environment, Food and Rural Affairs.
2 Sisters’ chairman Sir Charles Allen said he was “delighted” she was joining the group.
“She is without question one of Britain’s most respected and well-known business women and it is a real coup for us to have her in the board team,” Allen said.
“She brings unrivalled experience to 2 Sisters and her expertise and counsel will be invaluable as we look to continue to grow the business and realise our ambition of becoming one of the world’s best food companies.”
