A woman from Hartlepool has a new 161-word name after changing it by Deed Poll.
Dawn McManus, 41, promised to change her name to encourage fundraising for her charity, Red Dreams, which was set up after the death of her son.
She believes her new name - including the charity's name and people it has helped - could be the world's longest.
"Officially I should be called Red, but I appreciate some people will find it hard to embrace the change," she said.
She said her husband would probably "slip up" and call her Dawn rather than Red, her new first name, and Dreams, her new surname.
"He's not bothered I'm losing the McManus. He'll get used to it," Ms Dreams added.
The new name was registered via The Legal Deed Poll Service.
Tina Clough, spokesperson for The Legal Deed Poll Service, said: "We have processed a number of crazy name changes to date, but this is the longest one on record."
Ms Dreams said she did not know how the new name would fit on her passport or bank card but hoped she would be allowed to use initials or an abbreviated version.
