Fanderson is the official appreciation society for the works of British film and television producers Gerry and Sylvia Anderson.

Based in the United Kingdom, but with an international membership, it is a not-for-profit organisation run by a small committee of volunteers.

Paid members receive a subscription to the club magazine, FAB[4] (which is published three times a year – usually in March, July and November), as well as access to exclusive merchandise such as books, DVDs and soundtrack CDs.

[1][5][6] The club has also held conventions featuring guest appearances by actors and crew from the Anderson productions.

[7][8][9] In March 2014, the club severed ties with production company Anderson Entertainment (run by Anderson's widow, Mary, and their son, Jamie), stating, among other claims, that it was pursuing a "commercial agenda that is at odds with Fanderson".
