The Guest Book is an American anthology comedy television series created by Greg Garcia. Season 1 stars Charlie Robinson, Carly Jibson, Lou Wilson, and Kellie Martin, while season 2 stars 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 1 focuses on the renters of Froggy Cottage in the small mountain town of Mount Trace, while season 2 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.
