Hibernian have confirmed that Billy Brown will leave the club when his contract expires on June 30.
The former Hearts assistant manager was appointed to the same role at Easter Road in September 2011, taking over the role as caretaker manager in November of the same year after Colin Calderwood left the club.
In a statement on the club website Hibs' manager Pat Fenlon paid tribute to his departing assistant.
Fenlon said: "I'd like to thank Billy for the contribution he's made since I've been at the Club.
"His experience and knowledge of Scottish football is second to none and I was delighted that he agreed to stay on when Liam and I first came into the Club. With the reputation that Billy has I'm sure he'll be back in football before too long."
Billy Brown has previously been assistant manager to Jim Jefferies at Berwick Rangers, Falkirk, Hearts, Bradford and Kilmarnock.
