The 2011 SLC Super Provincial Twenty20 was the 4th and final season of the SLC Super Provincial Twenty20, the official Twenty20 domestic cricket competition in Sri Lanka. The tournament was scheduled as a replacement for the 2011 Sri Lanka Premier League, which was postponed to 2012. As such, the tournament had a different format from previous seasons, featuring five teams, instead of six, and was held sometime between 21 and 31 July 2011. The Sri Lanka Premier League replaced the SLC Super Provincial Twenty20.
The season comprised 10 regular matches, two semi finals and a grand final.
