The 2024 Dunlop Super2 & Super3 Series was an Australian motor racing competition for Supercars as a support series. It was the twenty-fifth running of the Supercars Development Series, the second tier of competition in Supercars racing. Since joining as a class in 2021 this marked at the same time as the seventeenth and final running of the Super3 Series before being axed in 2025 due to low grid numbers, the third tier of competition in Supercars racing (Officially in 2019 as the Kumho Tyre Super3 Series).

The Sandown 500 was originally set to be held on 22 September, but on 14 March, the event was moved forward a week to 15 September. This change has caused the Super2 event to also be moved forward a week.
