2023 Formula Nordic

The 2023 Formula Nordic season was the eleventh season of the Swedish-based single-seater championship, and the fifth independent of the STCC branding, following the formation of the series' association in the wake of the STCC promoter's bankruptcy in 2018. Formula Nordic continues to use the previous Formula Renault 1.6 chassis and engines, as it used to go under the name of Formula Renault 1.6 Nordic before Renault Sport dropped its support for the 3.5 and 1.6 classes in late 2015. The season began on 6 May at Mantorp Park, and concluded on 1 October at Jyllands-Ringen after 17 races held over seven rounds. This was the third season with Yokohama as the series' tyre supplier.

Race calendar and results
The season began on 6 May at Mantorp Park, and concluded on 1 October at Jyllands-Ringen, on a first-time visit to Denmark for the series, after 17 races held over seven rounds. The rounds at Anderstorp, Karlskoga and Jyllands-Ringen were held together with the F4 Danish Championship, after an agreement between the two series was reached in order to have combined grids. For all stand-alone rounds, the fastest time in qualifying clinched pole position for the first race, whereas the use of reversed grid races for the final race, where the top 6 were inverted, was continued. In three-race rounds, the 2nd fastest time in qualifying held pole position for the middle race. The rounds co-hosted with the F4 Danish had particular rules. The Anderstop double-header had the grid for race 1 according to the fastest lap in qualifying and the grid for race 2 according to the fastest lap in race 1. In the Karlskoga triple-header, grids for races 1 and 2 were made according to the fastest and 2nd fastest laps in qualifying respectively, while the grid for race 3 was set according to the fastest lap in race 2. For the Jyllands-Ringen triple-header, the grids for races 1 and 2 were made similarly to Anderstorp, whereas the grid for race 3 was set by a combination of the results in races 1 and 2.
