Financial terms of the deal were not released Friday. Boykin has appeared in 39 games with 11 starts in three seasons for the Packers, recording 57 catches for 731 yards and three touchdowns.
His best season came in 2013 when he had 49 receptions for 681 yards and three TDs.
The 6-2, 215-pound Boykin joins Ted Ginn Jr. as the second free agent wide receiver the team has signed this offseason.
The Packers decided not to tender Boykin, a restricted free agent, a right-of-first-refusal contract worth $1.542 million in March, allowing him to become a free agent.
Boykin played his prep football at Butler High in Charlotte.
