"Lorraine brings valuable experience, skills and new perspectives that will help us to transform the council and continue to deliver for our residents.
"We have an ambitious programme ahead to improve the environment, economy, health outcomes and opportunities for everyone in Cheshire East and I am sure that Lorraine will help us in delivering that."
Councillor Craig Browne, deputy leader of the council, said: "Cheshire East, as a borough and as a council, has enormous potential and I look forward to working with Lorraine to achieve that potential. Lorraine will play a vital role in leading the council's staff and in building on our relationships with key partners in business, health and other public services.
"We have a high-performing economy and want to ensure we have a high-performing council to match."
Lorraine said: "I am delighted to be joining Cheshire East Council as chief executive. This is a really exciting time to be joining the council and I am looking forward to working with elected members, staff and partners to serve residents and communities."
Lorraine O'Donnell will start work at the council on 30 March.
