Arcon is an annual gaming convention in Oslo, Norway. It is arranged by the two gaming clubs called Ares (both of them), as the name reflects ("Ar-con"), in the usual style of gaming conventions. Arcon is Norways largest convention of this type, and is held at Oslo University at Blindern the weekend closest to midsummer eve.

Arcon is a quite old convention, this year (2001), Arcon 17 is held (which means that unless they skipped any years, the first Arcon was held in 1985).
