The 2017 Blancpain GT Series Sprint Cup was the fifth season of the Blancpain GT Series Sprint Cup following on from the demise of the SRO Group's FIA GT1 World Championship (an auto racing series for grand tourer cars), the fourth with the designation of Blancpain Sprint Series or Blancpain GT Series Sprint Cup.
At the annual press conference during the 2016 24 Hours of Spa on 29 July, the Stéphane Ratel Organisation announced the first draft of the 2017 calendar. The series started at Misano on 2 April and ended at the Nürburgring on 17 September. Zandvoort would make its return on the schedule after a one-year absence, replacing the round in Barcelona, but on 7 November the SRO announced the finalised calendar, confirming Zandvoort had been replaced by Zolder. The finalised calendar also showed the series would return to the Hungaroring.
