The eatery, which has around 900 locations in the UK, made the announcement via a social media post titled 'KFC You Later'.
'Minimize food waste'
"We're committed to doing this in the right way and are focussed on closing responsibly - to prepare our restaurant teams, help our suppliers and minimize food waste," the company wrote.
"Restaurants will begin closing from now. They will all close by Wednesday, March 25 until further notice. It's not a decision we've taken lightly, but it's in the best interests of both our incredible teams and all the fans that love our chicken."
The company also stated that it will find 'safe and efficient' ways to distribute any unused food, which will include working with its Food Donation Scheme partner.
KFC has followed in suit of McDonald's, who announced yesterday it would also close all of its UK restaurants amid the COVID 19 outbreak.
"This is not a decision we are taking lightly, but one made with the well-being and safety of our employees in mind, as well as in the best interest of our customers," the company wrote.
"We will work with local community groups to responsibly distribute food and drink from our restaurants in the coming days."
