Villas-Boas was left seething after both JosÃ© Bosingwa and Didier Drogba were sent off in the first half of their 1-0 loss at Loftus Road.
The Chelsea boss described referee Foy’s performance as “very very poor” after the game and claimed the official’s display affected the result.
“Villas-Boas has been charged with improper conduct,” confirmed an FA statement. “He has until 1600 GMT on 15 November to respond to the charge.”
Speaking after the defeat, Villas-Boas said: “The ref was poor, very very poor. And it reflected in the result.
“I spoke to him at the end and I was very aggressive to him. I don’t care if he’s OK or not.
“Everyone can have a bad day, but this was not a bad day for us. It was a good day for us and a bad day for the referee.”
