Ironsworn is an indie role-playing game written and self-published by Shawn Tomkin. Its Ironlands setting is low fantasy, set in a rugged frontier.

Ironsworn is distinct from most traditional tabletop role-playing systems for having a well-developed solo mode and is one of the most popular solo tabletop role-playing games.

Ironsworn is an indie role-playing game designed by Shawn Tomkin. He said that the game was developed over a span of three years, while he was playtesting and collecting feedback from players in the Google+ tabletop role-playing community. He didn't expect the game to become successful.

The German tabletop role-playing games publisher System Matters translated and published Ironsworn in 2021. The game was a commercial success for them, indicating interest for Ironsworn in the German-speaking tabletop role-playing games community.

In 2024, 500 Nuances de Geek, a small independent French publisher of games and books, started a campaign on Ulule, a French crowdfunding platform. The goal of the campaign was to translate and publish Ironsworn and Ironsworn: Starforged in French. Soon after starting the campaign, they released a free PDF, as the original English version is also available as a free download. In regard to Ironsworn, the goal of the campaign was to produce a printed edition, with almost identical contents to the free digital edition.

Ironsworn is set in the Ironlands, a Greenland-adjacent, Norse-inspired low fantasy setting.

Player characters are built by allocating a specific number of points to the five different stats. These are edge, heart, iron, shadow, and wits.

Apart from the starting stats, there are also trackers for health, spirit, and supply.
