The National Phobics Society has changed its name to Anxiety UK in a bid to make it easier for people to understand its work.
The move is part of a complete rebrand of the charity, which includes a new website and logo.
Nicky Lidbetter, chief executive of Anxiety UK, said the charity's old name gave the wrong impression of what it did.
"Anxiety UK does much more than support sufferers of phobias and our old name was misleading in this respect," she said.
"We offer advice, treatment and therapies to sufferers of all anxiety conditions. We will continue to help those suffering from phobias, as anxiety is at the core of all these conditions."
The charity was formed in 1970 by an agoraphobia sufferer.
