The 23-year-old has signed a one-year deal and will link up with manager Derek Adams, who previously signed him for Ross County last summer.
Jervis, who started his career at Birmingham City, had made 30 appearances for County last season, following spells at Portsmouth and Elazıgspor.
He has become Plymouth's second signing of the summer, after Gary Sawyer's return to the club last week.
