Derry, who has continued with the restaurant chain since it was acquired by Greene King in August 2007 for £68.1m, will be replaced by current operations director Richard Morris.
Loch Fyne founders Derry and Ian Glynn are widely known for transforming Scotland's Loch Fyne restaurant business, which now comprises 49 outlets located mainly in the South-east, and also for championing sustainability.
The duo were recognised for successfully establishing upmarket fish restaurants in the UK casual dining market with a Catey Group Restaurateur of the Year award back in 2005.
