The Wildsea is a tabletop roleplaying game published by Mythworks. The game was released in February 2022.

The Wildsea takes place in a post-apocalyptic fantasy world that has been overrun by rapidly-growing mile-high trees and other vegetation in an event called "the Verdancy" that occurred 300 years before the game begins.^[1] Key to this growth is a toxin called crezzerin (present in the majority of the setting's flora), the mutative properties of which are responsible for creating most of the game's playable and wildlife species.

After the Verdancy, the world of the Wildsea bears similarities to a nautical one - mountains have become islands upon which ports towns are built, and travel happens by way of ships that can pull or otherwise propel themselves on top of the tree canopies (such as with large mechanical chainsaw prows).^[2] The players in the game are a crew of so-called wildsailors, creating and customizing their own ship in addition to their personal characters.

The Wildsea was originally made available as a series of free quickstart documents in 2020, before a Kickstarter campaign to fund the development of the core rulebook launched later that year.^[1]

After the publication of the core rules in February 2022, several other supplements have been released, such as the Storm & Root expansion (which focuses on exploring the lower layers of the sea in submersible vessels, and on the skies above in airships), pre-made scenarios (One-Armed Scissor aimed at new players, and Red Right Hand intended for experienced groups).

In 2023, The Wildsea won a silver ENNIE Award for Best Writing.^[3]

In his 2023 review, Dave Thaumavore called the game "one of the most original, mechanically interesting and well-laid out games [he's] ever come across" and "almost unbelievably illustrated" with its "evocative art that sells the setting completely".^[4]

In his 2024 review of the game, Quintin Smith of Quinns Quest described the Wildsea as "taking the genre of fantasy and then ripping out all the tropes" and letting the players "experience awe and wonder all over again," praising its unique worldbuilding, tone, artwork, writing, layout, and rules (though criticizing the game's ship traveling system and the mechanics for healing).

The game has been cited as an inspiration in several subquently-released tabletop roleplaying games - the authors of Daggerheart gave it a "special appreciation," citing The Wildsea's Reaches (pre-defined areas of the game world with unique features) as influencing Daggerheart's own section of Campaign Frames,^[5] as well as being one of the inspirational works behind the Natural Fantasy supplement for Fabula Ultima.^[6]
