The defendants were convicted for participating in clashes between Morsi supporters and opponents that killed 12 people in the Mediterranean city of Alexandria last July, after the military overthrew the Islamist president, the sources said.
Since Morsi's ouster, his supporters have been staging weekly protests calling for his reinstatement.
The rallies have often degenerated into violent street clashes with security forces and civilian opponents.
Eleven defendants were given 10 years in jail, 13 were jailed for seven years, 55 were jailed for five years and seven acquitted, the sources added.
