Harry and Oprah are believed to be good friends and she attended his Royal Wedding to Meghan Markle last year.
The new series will launch on Apple in 2020.
Prince Harry said: "I truly believe that good mental health - mental fitness - is the key to powerful leadership, productive communities and a purpose-driven self. It is a huge responsibility to get this right as we bring you the facts, the science and the awareness of a subject that is so relevant during these times.
