Event organisers blamed the cancellation on a "key investor" withdrawing and poor ticket sales.
"This is a very sad conclusion to our passionate efforts to develop an interesting and credible addition to the UK festival market," they said in a statement.
"Unfortunately, Wild in the Country has become the latest in a series of festivals that have suffered from a unique and well-documented set of market forces this summer."
Bjork pulled out of the festival earlier this week, citing stage problems as the reason for her withdrawal.
Wild In The Country was scheduled to take place on July 5. Its lineup included Soulwax, Battles, Pendulum, Sasha and Foals.
Organisers added that they would attempt to refund all fans who bought tickets for the bash.
