2023 New Zealand Motocross Championship

The 2023 New Zealand Motocross Championship season was the 49th New Zealand Motocross Championship season.

The series had four rounds across the country, running from early February to late March. This was the first championship since 2021, as the previous year's competition was cancelled due to the COVID-19 pandemic.

Hamish Harwood was the reigning champion in the MX1 category, after taking his fifth national title in 2021. However, he would eventually finish as runner-up to Maximus Purvis, who took his first MX1 national title. In the MX2 class, Cody Cooper won his tenth senior national title overall, after dropping back into the class for 2023.

The third round of the championship was originally scheduled to take place at the Hawke's Bay track. Following Cyclone Gabrielle, the round had to be cancelled with the final round at Taupō being converted into a double-header in its place.
