Tirant lo Dau is a Catalan-language role-playing community founded in 2020, bringing players and creators together to enjoy and develop role-playing games in Catalan. Its central activity is a programme of monthly online games: narrators can submit proposals from the 15th of each month, and players can browse available sessions and sign up from the 23rd. The community also hosts live games and related events, including in-person gatherings.

Tirant lo Dau supports access to role-playing material in Catalan by maintaining a record of rights-free resources, translating new material through its dedicated group, and creating original content. Its website features resources such as a fanzine, translations and locally produced work, alongside invitations for visitors to contribute translation ideas or propose games. The organisation also publishes news, reviews, interviews and articles about role-playing, and has organised talks, charity activities and other community events. Through these initiatives, Tirant lo Dau promotes play, creative collaboration and a growing body of role-playing content in the Catalan language.
