Gold Coast Mayor Tom Tate says fraudsters are using his name and likeness to solicit funds.
Councillor Tate says letters seeking donations for beach repairs have been sent to residents on Chevron Island and at Palm Beach.
A woman has told the council the letter she received was said to be from the mayor.
It asked for money to be transferred into an anonymous account.
Councillor Tate has been seeking Queensland Government funds to fix severely eroded beaches.
He says the scam is an attempt to cash in on public support for those efforts.
Cr Tate says the council will never write seeking donations and anyone who is approached should report the matter to police.
