The company, titled Studio Ramsay Global, will produce and distribute culinary and lifestyle programmes.
Ramsay will act as co-owner of the new company and oversee offices in London and Los Angeles.
The celebrity chef and renowned restauranteur has partnered with Fox in the past to create programmes like MasterChef, MasterChef Junior, and Hell's Kitchen.
Ramsay said: "This is an incredibly exciting opportunity, not just for me, but for the team at Studio Ramsay.
"We’ll be creating food and lifestyle ideas, but also developing an incredible new talent pool of food, drink and industry leaders to create our own culinary talent branch.
"I couldn’t be more excited about this new global partnership with Fox.
"After 16 incredible years working together, this takes Studio Ramsay to the next level."
Chief executive of Fox Entertainment, Charlie Collier, added: "Gordon Ramsay is the definition of a partner and friend.
"He’s also the genius behind a global brand that represents integrity and excellence in food, lifestyle and so much more.
"Fox Entertainment is honoured to build upon its long-term relationship with Gordon as, together, we introduce Studio Ramsay Global.
"Gordon has been an important part of the Fox experience for years, bringing an energy, entrepreneurial spirit and attitude that fits beautifully at Fox."
