Hibs will immediately begin their search for a successor. We take a look at some of the names likely to be mentioned over the coming days and - potentially - weeks.
5. Stephen Robinson
The Motherwell boss has successfully kept his club away from the relegation battle during his time in charge and has taken 'Well to two major finals. Also linked with Hearts.
6. Jack Ross
Was being linked with Hibs almost immediately after being sacked by Sunderland. Did well at Alloa and St Mirren but is also rumoured to be on Hearts' radar
7. Grant Murray
Highly regarded during his spell as development team boss and got promoted to first team coach after leading the U20s to a league and cup double.
8. John Doolan
First-team coach under Alan Stubbs and has been tipped for a return before, but has never held an outright management / head coach role. Currently at Accrington but retains a lot of affection for Hibs
