Mourinho was one of a number of names to be linked with the Manchester United job after David Moyes was removed from his position earlier this week, but Mourinho has declared that he has no interest in moving to Old Trafford.
Asked being asked if he would consider taking the job, the 51-year-old told reporters: "Of course not. How can somebody think about it?
"I left Real Madrid to come to Chelsea specifically. I signed a four-year contract with Chelsea.
"I told Chelsea that they never have to worry about me because I don't want to leave. I stay as long as the club wants me to stay."
