"WE just want him home," Alanvale mother Lillian Watkins says of her son Christopher Dean Watkins, who was last seen about 12 days ago.
Mr Watkins, 28, was reported missing to police on Saturday.
He had been staying with friends at Mayfield.
Mrs Watkins said she did not know what had happened to her eldest son.
"It's just out of character for him not to be in contact with his two brothers," she said.
"They are very close. His family is missing him.
"I got concerned myself on Monday last week when I knew that he did not access his bank account, but his brother Sean had concerns before that.
"I just want him to come home or make contact with me or Sean or his dad Ray, just to let us know that he is OK, or if there is a particular reason why he has gone away for a while.
"Please contact us and let us know you're OK."
Mr Watkins is about 170 centimetres tall, of medium build, with a bald head, blue eyes and tattoos.
Police urge anyone with information about his whereabouts to call Launceston police on 63363701 or Crime Stoppers on 1800333000.
