Growing Up Brady: I Was a Teenage Greg is a 1992 autobiography written by actor Barry Williams with Chris Kreski and a foreword by Robert Reed.

Two editions of the book exist: the first edition details his Brady co-stars attending his 1990 wedding to Diane Martin; that marriage ended in divorce two years later; the second edition, published several years later, replaces the references to Martin with his impressions of the feature films The Brady Bunch Movie and A Very Brady Sequel, and reflections on Reed's death in 1992 due to cancer and the subsequent media frenzy over the news that Reed had been diagnosed as HIV positive (misreported as AIDS) prior to his death.

[1] The book was adapted into a made-for-television film called Growing Up Brady that aired May 21, 2000 on the NBC network.
