The 2025 Australian National Trans Am Series (commercially titled 2025 Trico National Trans Am Series) was a national motor racing series featuring conducted using TA2-class cars. The series was organised by Australian Racing Group and is one of two national racing series conducted using this car class; the other was the TA2 Racing Muscle Car Series. It was sanctioned by Motorsport Australia.
The series schedule has changed significantly with the SpeedSeries not running in 2025. The series ran as a support category at three Supercars Championship events, notably the Adelaide 500.
Also notable was a joint race with the other national TA2-based series, the TA2 Racing Muscle Car Series, at the Bathurst Six Hour, which category organisers hope to have a combined grid "in the vicinity of 40 cars".
