Mohamad bin Mohamad Khalid, known professionally as Mamat Khalid (6 April 1963-24 October 2021) is a Malaysian screenwriter, film director, and occasional actor. He is the younger brother of cartoonist Datuk Mohammad Nor Khalid, better known as Lat.

As a young boy, he used to go to the cinemas every other day to catch the latest movies. Unfortunately, his hobby did not resonate well with his father, who banned him from frequenting cinemas even on his deathbed. However, that did not break the young Mamat's passion into films.
