The 2013 Porsche Mobil 1 Supercup season was the 21st Porsche Supercup season. It began on 12 May on Circuit de Catalunya and finished on 3 November at Yas Marina Circuit, after nine races, all of which were support events for the 2013 Formula One season. A new car was introduced for the season as the Porsche 991 – the internal designation for the seventh-generation Porsche 911 – replaced the Porsche 997.
Ahead of the final round of the series in Abu Dhabi, Monégasque-based British driver Sean Edwards held a championship lead of eighteen points over Denmark's Nicki Thiim, with Michael Ammermüller of Germany the only other driver to remain within contention for winning the title. Edwards was killed on 15 October 2013 at Queensland Raceway in Willowbank, Australia, while instructing a member of the public at a private test session. Thiim ultimately won the championship, after he won both races in Abu Dhabi; Edwards ended up second overall, finishing three points ahead of Ammermüller.
