The report, citing mashreghnews.ir, does not specify when the court issued its verdict for Hossein Derakhshan, who has been in custody for two years.
Derakhshan was convicted of cooperation with hostile countries, spreading propaganda against the ruling establishment, promoting counterrevolutionary groups, and insulting Islamic thoughts and religious figures, AP reports.
Derakhshan, nicknamed Hoder, was a leading figure in the Persian-language blogosphere and was credited with helping blogs gain popularity in his native Iran -- so much so that he was dubbed Iran's "Blogfather."
He was arrested in 2008, shortly after returning to Iran following time living in Britain and Canada.
Derakhshan holds dual Iranian-Canadian citizenship.
Recent unconfirmed reports had suggested Derakhshan had been sentenced to death. Derakshan's mother said recently that prosecutors had asked for the "maximum penalty" for her son.
Mashreghnews.ir is said to enjoy close ties to the office of Iranian President Mahmud Ahmadinejad.
