Ironclaw is a series of tabletop role-playing games created by Jason Holmgren of Sanguine Games, this series features anthropomorphic characters in a setting inspired by class and religious conflicts during the Italian Renaissance.

[2] As of 2019, the game has been in continuous publication, with various add-on books such as The Book of Monsters featuring Ursula Vernon,[3] and is run at furry conventions such as Furry Fiesta,[4] Midwest FurFest and Anthrocon.

Ironclaw uses a system where attributes of characters are matched to different polyhedral dice.

[5] These attributes include a character's physical, mental, and social capabilities, in addition to the abilities associated with their species.

[6][7] This system was later used in Sanguine's other role-playing games, including Jadeclaw.
