The attacker, currently with Turkish side Trabzonspor, started his career with the Ligue 2 side, where he made his debut at 16 and spent four years with the team before moving on to join Guingamp and latterly Lyon and Chelsea.
The 33-year-old had his first interaction with the board on Saturday and will begin to make long-term investments into the club.
A statement on the club's official website read: "Florent Malouda today participated in the Board of Directors of Berrichonne de Chateauroux, his first club to which he has always remained very close.
"He will soon be integrated into the management board as his career develops. This return is a new, unique and rare gesture of a great player going back to where it started."
