"Although it is very hard to do - the hardest decision of my life - I believe that, after 10 years, it is the right time for me to step aside to allow new leadership, energy and ideas to take the club forward into this exciting new era," he said.
"I believe in the positive force of change, both for me and for the club. While this is the most difficult and challenging course for me, I am excited to see what the future holds for this great club."
Gazidis will leave Arsenal by the end of October and become AC Milan chief executive on December 1.
