The Parkinson's Disease Society is changing its name to Parkinson's UK as part of a rebrand that it hopes will help raise awareness of the disease.
The charity said the new name and brand, which will be introduced in April, had been developed because people, including GPs and health professionals, did not know enough about Parkinson's or what the charity did.
The charity said it hoped to raise £110m over the next five years to help find a cure for the disease.
The new identity will be launched with a series of posters featuring images of people suffering from the disease.
Steve Ford, chief executive of the charity, said: "The old brand didn't fully reflect what we do and the hope is that our new brand will show that our members are at the heart of our work.
"The views of people affected by Parkinson's have helped us to clarify our vision for the future to find a cure and improve life for everyone affected by the disease," he said.
"We have ambitious plans focused on delivering that vision. Our brand is a big part of this."
