Over the past seven seasons, Chapple has steered Lancashire to three second-placed finishes in the County Championship, the Division Two title in 2019, and three appearances at T20 Blast Finals Day.
Commenting on his departure, which brings to an end his 30-year association with Lancashire, Chapple said: "I am immensely proud of what we have achieved at Lancashire over the years and I would like to thank all the players, staff and members and supporters for the support I've received – both as a player and as a coach - during my career at Emirates Old Trafford.
"I feel that now is the right time in my career to explore and pursue other coaching opportunities and I wish the club all the best for the future."
Director of cricket Mark Chilton praised Chapple's lengthy commitment to Lancashire, adding: "Glen has been an incredible servant to Lancashire Cricket over the past 30 years – as a player, captain and most recently as head coach - and on behalf of the club, I'd like to thank him for everything he's achieved.
"He will go down as a legend of the club from what he achieved during his playing career and has overseen a sustained period of success over the last seven years as head coach.
"Glen's shown a relentless commitment and passion to the Red Rose during his time as head coach and we wish him every success in the next steps of his career."
