Emirati singer Hussain Al Jassmi is to serve as goodwill ambassador for Emirates Red Crescent.
The popular performer was awarded the role at the opening of the charity's new headquarters in Abu Dhabi.
"The paths of hope are open and humanity drives us to serve the people everywhere," he said.
"Thank you ERC for this confidence and for giving hope for a better life."
Al Jassmi, 39, who comes from humble beginnings in the port town of Khor Fakkan, became the first Arab artist to perform at the Vatican's annual Christmas concert last year.
Emirates Red Crescent is among the country's largest charities, supporting relief efforts at home and abroad, and serving as a government-approved partner for residents running their own volunteering and charity activities.
