Hamza, who is blind in his left eye and has a prosthetic hook in place of his right hand, was indicted originally in 2004 one numerous counts that were terror-related, including attempts in 1999 as well as 2000 to establish a Bly, Oregon jihad training facility.
He was found guilty as well for plotting the kidnapping of westerners located in Yemen during 1998.
Hamza, also known as Mustafa Kamel Mustafa denied the charges against him and testified during his trial, saying he had merely acted as a mouthpiece for the movements supported by Islamists.
No comment was made by his attorney, nor was a request for comment on the ruling released.
On Tuesday, Preet Bharara the United States Attorney in New York said Hamza had been convicted for the comments he has made, but for what he has done.
Abu Hamza, said Bharara, was not only a preacher of his faith, but a trainer to terrorists. The civilian judicial system has once again proven itself worthy of the task in trying an alleged terrorist and arriving at a result that was swift, fast and fair.
British authorities first arrested Hamza in 2004 but he was not extradited to the U.S. until 2012 to stand trial following a long legal battle.
Hamza has been associated with and preached at a mosque that is highly controversial that was at one time attended by Richard Reid the shoe bomber.
The notorious preacher of hate likely will die in jail in the U.S. following his conviction.
The conviction brings to an end a battle of 10 years to have Hamza extradited to the U.S. from the UK to stand trial.
It is thought that the UK will now start legal proceeding to strip the convict of his British citizenship, which will end his 34-year tie to the UK.
The jury found the former imam at a mosque in London guilty on each of the 11 counts following a trial of five weeks.
