He passed away at Knockmoyle Lodge nursing home, just outside the Co Tyrone town, on Sunday morning.
Twenty-nine people were killed and many more injured in the Real IRA attack in August 1998.
Mr Rush's wife - who was known as Libby - owned a pine and canework shop in the town and was killed as she served customers after her shop took the full force of the blast.
Laurence and Elizabeth were childhood sweet hearts and married when they were both 18.
Following the bombing, Mr Rush said "they have not only destroyed my wife, they have destroyed my life". He became a tireless campaigner for justice for the victims.
Mike Nesbitt of the UUP has expressed his condolences.
"No one who heard his incredibly passionate, emotional and articulate statement about the loss of his wife could fail to be moved by what he said," the Strangford MLA said.
"It was as powerful an assessment of the impact of terrorism as you will ever hear.
"He has carried the burden of loss for many years now, and I am in no doubt he felt his own life ended that day, the 15 August, 13 years ago, when he lost his beloved Elizabeth.
"Those who carry out and support terrorism should reflect on the life sentences they impose on people like Laurence Rush, and we should all bear in mind the impact this news will have on those most deeply impacted by the Omagh bomb and keep them in our thoughts at this time."
Mr Rush passed away at the nursing home where we was being cared for after suffering a stroke some years ago, surrounded by family.
