The 2018 Mediterranean Games (Catalan: Jocs Mediterranis de 2018, Spanish: Juegos Mediterráneos de 2018), officially known as the XVIII Mediterranean Games (Catalan: XVIII Jocs Mediterranis, Spanish: XVIII Juegos Mediterráneos) and commonly known as Tarragona 2018, was an international multi-sport event held from 22 June to 1 July 2018 in Tarragona, Catalonia, Spain.

Tarragona was announced as the host city at the ICMG General Assembly in Mersin, Turkey, on 15 October 2011.

The International Committee of the Mediterranean Games (ICMG) announced in November 2016 that Tarragona was postponing its hosting of the Mediterranean Games from 2017 to 2018 due to funding problems caused by Spanish political and economical instability.
