Evans, who was slowed by an ankle injury last season, has 317 career tackles.
The move reunites Evans with Falcons coach Arthur Smith and former Titans defensive coordinator Dean Pees.
The Falcons lost inside linebacker Foye Oluokun in free agency. He led the NFL in tackles last season and signed with Jacksonville.
The Titans elected not to exercise Evans’ fifth-year option last offseason, which led to him becoming an unrestricted free agent.
