The 2017 Jerez FIA Formula 2 round was a pair of motor races held on 7 and 8 October 2017 at the Circuito de Jerez in Jerez de la Frontera, Spain as part of the FIA Formula 2 Championship.

It was the tenth and penultimate round of the 2017 FIA Formula 2 Championship.

After a disappointing round in Monza for championship leader Charles Leclerc with a total of 0 points to his name, the Monégasque driver took yet another pole position and prematurely clinched the championship title by winning his sixth race of the season with three races to spare.

With only one weekend to go, Leclerc was leading the championship with an unassailable lead by 60 points over current runner-up Oliver Rowland.

As of 2022, Leclerc holds the record for the most pole positions in a Formula 2 season with eight.
