The Catan Scenario and Variant Guide is a guide to all officially released scenarios and variants for Catan, a board game created by Klaus Teuber in 1995. The game has grown over the 30+ years into a modern classic and a gateway game into the world of board gaming.

The Guide originally started as a PDF document, but largely became unmanageable due to spanning over 450 pages when last released in 2017. For this Live version, the Guide has been completely rewritten to make it easier to maintain.

In addition to a rules summary of each scenario and variant, if the scenario is not available in English, then a best effort is made to replicate the scenario using only components available in English.
