Matthew Maynard has been re-appointed as Glamorgan head coach on a three-year contract.
The former Test batsman was interim coach in 2019 and was also in charge between 2008 and 2010.
Under his guidance the county just missed out on promotion as they finished fourth in the second division of the Championship, but won just one T20 match.
He has captained Glamorgan and played 18 times for England.
Maynard's coaching career includes a spell as England assistant, three years as Somerset director of cricket and time in charge of South Africa's Nashua Titans and the Caribbean side St Lucia Zouks,
As a hard-hitting batsman, he led Glamorgan to the Championship title in 1997, as well as playing in one-day league victories in 1993, 2002, and 2004.
He initially returned to Glamorgan for a second coaching spell as batting consultant in 2017 under Robert Croft, before taking over the main job for the 2019 season.
"We showed some improvement in the Championship and One-Day Cup but it's important we continue that upward trajectory and take our form across into the Vitality Blast next season," said Maynard.
"I live eight miles away from the ground, it's a great place to work, I love the club, it's part of me, so to try to help it regain first division status in the Championship and bring more silverware, that's the goal over the next three years.
"There's going to be a period of transition, we've got some bowlers coming towards the end even though they can still perform highly, so it's looking after them and developing the younger talent to make sure they're up to scratch to take over."
The county did not advertise the job after Maynard's interim period.
"We considered that option but once we'd done our reviews and got our feedback it became apparent we had the right guy here, and Matt carrying on the work he'd started was our best course of action," said Glamorgan's director of cricket Mark Wallace.
"The massively positive feedback was from the players who've come in (in 2019), Marnus Labuschagne, Billy Root and Charlie Hemphrey, their feedback was very strong.
"We had a marked upturn last year albeit it wasn't the finish to the season we would have wanted, but there was an upturn in our fortunes and the decision is to try to continue that way."
The news has been welcomed by Chris Cooke, Glamorgan's captain in the Championship.
"I think I speak on behalf of all the players when I say we're chuffed Matt's got the job," Cooke told BBC Wales.
"He's done some really good things with the team this year and we're excited to keep on working with him."
Cooke will relinquish the One-Day Cup captaincy after being picked by Birmingham Phoenix in the draft for the Hundred competition which runs at the same time.
