The 2013 Super Rugby season was the third season of the new 15-team format for the Super Rugby competition involving teams from Australia, New Zealand and South Africa. The tournament was won by the Chiefs, who defeated the Canberra-based Brumbies 27–22 in the competition final. For sponsorship reasons, this competition is known as FxPro Super Rugby in Australia, Investec Super Rugby in New Zealand and Vodacom Super Rugby in South Africa. Including the past incarnations as Super 12 and Super 14, this was the 18th season of the Southern Hemisphere's premier domestic competition. Conference matches took place every weekend from 15 February until 13 July – with a break between rounds 17 and 18 for internationals games – followed by the play-offs series that culminated in the final on 3 August.

Super Rugby is a men's professional rugby union club competition involving teams from Australia, Fiji, New Zealand, and the Pacific Islands. It has previously included teams from Argentina, Japan, and South Africa. Super Rugby started as the Super 12 in the 1996 season with 12 teams from Australia, New Zealand, and South Africa, building on competitions dating back to the South Pacific Championship in 1986. The Super 12 was established by SANZAR after the sport became professional in 1995. After the COVID-19 pandemic forced the competition to split into three, the reformed competition in 2021 only included teams from Australia, New Zealand and the Pacific islands.
