The Guest Book is an American anthology comedy television series created by Greg Garcia. Season one starred Charlie Robinson, Carly Jibson, Lou Wilson, and Kellie Martin, while season two starred Jibson, Eddie Steeples, Kimiko Glenn, Jimmy Tatro, and Dan Beirne.

The series centers on the lives of the employees of, and visitors to, vacation rental properties: season one focuses on the renters of Froggy Cottage in the small mountain town of Mount Trace, while season two follows the renters of Barefeet Retreat in the oceanside town of Mabel Beach. The regular cast plays residents in the town(s), while each episode is focused on a different guest star who plays an out-of-town vacationer. Garcia, who based the show on his habit of writing fake guest-book entries while on vacation, wrote all the episodes, and makes brief season-two appearances as street beggar Homeless Jack.

The series premiered on TBS on August 3, 2017. On September 13, 2017, TBS renewed it for a second season, which premiered on October 23, 2018.

Garcia tweeted on September 12, 2019 that TBS had cancelled the series.
