The Chelsea manager admitted a charge of improper conduct after he was sent to the stands by referee Anthony Taylor during the Blues' controversial 4-1 win at Stamford Bridge.
A statement from the FA read: "Chelsea manager Jose Mourinho has been fined £8,000 after he admitted a breach of FA Rule E3 in that his behaviour in or around the 69th minute of his side's game against Cardiff City on 19 October 2013 amounted to improper conduct.
"The fine is the standard penalty for the offence."
Mourinho sat with surprised supporters after being ordered from the touchline midway through the second half after repeatedly voicing his frustration to Taylor and fourth official Trevor Kettle.
