The Championships of the Small States of Europe (CSSE) is a biennial competition in outdoor track and field organised by the Athletic Association of Small States of Europe (AASE).
The idea for a stand-alone athletics championships for European small states arose through discussions with AASE president Edwin Attard and European Athletic Association president Hansjörg Wirz.
The European small states traditionally sent a combined team to the European Team Championships, but following that competition's change to a biennial format a gap in the sporting calendar emerged.
Competing nations used the competition to help their athletes push for qualifying standards to the European Athletics Championships and Summer Olympics.
