Bowden, who has worked previously for Ipswich Town and Saatchi & Saatchi, will take over from David East following his departure from the Division Two outfit at the end of 2012.
Bowden, who will start his new job early in the 2013 season, told www.essexcricket.org.uk: "I'm really looking forward to joining the team at Essex and working with them to create the success that Essex Cricket deserves."
Nigel Hilliard, chairman of Essex Cricket, said: "Derek has a wealth of experience in the commercial and sporting world, which will be of great benefit to the club at a time when we are embarking on a major redevelopment of the Essex County Ground.
"Once completed the stadium will be a fitting centrepiece to the new city of Chelmsford."
