Carlisle had two years left on his contract after being Dallas's head coach for the last 13 seasons.
"After a number of in-person conversations with Mark Cuban over the last week, today I informed him that I will not be returning as head coach," Carlisle said in a statement. "This was solely my decision."
"Dallas will always be home, but I am excited about the next chapter of my coaching career.
