Former Armagh captain Ciaran McKeever will take charge of the county's Minor panel in 2019.
The 35-year-old's appointment was ratified at a county board meeting on Wednesday night.
The St Patrick's Cullyhanna clubman succeeds Paul McGrane in the role.
McKeever retired from inter-county football in 2017 after a 14-year career in which he won four Ulster titles and represented Ireland three times in the International Rules series.
He captained Armagh to All-Ireland Under-21 success in 2004 and also won Division One and Division Three titles with the county.
Armagh suffered an early exit from this year's Ulster Minor championship following a three-point loss to Down in round one before a heavy defeat by Derry in the provincial qualifiers.
