Moonhaven was developed as part of AMC Studios' 'scripts-to-series' model, with a writers' room opening in March 2021 for creator Peter Ocko's project before it received a greenlight order from AMC on May 11, 2021.

Dominic Monaghan signed on in July 2021 to star as the lead opposite Joe Manganiello, with Emma McDonald announced to headline the series alongside him.

Kadeem Hardison and Yazzmin Newell were announced as series regulars, with Newell joining the cast in September 2021, a couple of months after the rest of the main cast was set.

The series holds a 67% positive rating from 18 critics on Rotten Tomatoes with an average score of 5.9/10, and a Metacritic score of 74/100 based on 10 critics, indicating 'generally favorable' reviews.

Rotten Tomatoes' critical consensus described the show's utopia as 'often more goofy than harmonious,' while noting it would appeal to fans of idiosyncratic sci-fi.

On July 28, 2022, AMC+ reported that Moonhaven had been renewed for a second season, but by December 3, 2022, the network reversed that decision and canceled the series entirely.
