Top Doorslammer is a professional (Pro) class of Australian drag racing. It caters to full-bodied racing sedans which are replicas of Australian or US production vehicles. The class uses 514 cu. in. displacement (8.5-litre), mechanically supercharged V8 engines which are fueled by methanol. The minimum weight break for these vehicles is 2700 lbs (1225 kg). It is similar to the Pro Modified class as defined by the NHRA.

Top Doorslammer is regulated by ANDRA, and is considered a Group 1 or professional category. It is the fastest sedan based category in the world, using replicas of front-engined production sedans, coupes, station wagon and utility vehicles usually produced by Holden, Ford, Dodge, Studebaker and Chevrolet. As its name suggests, these cars have operational doors, therefore Funny Car style bodies are not allowed in this class.

Some notable drivers competing in this category are John Zappia, Peter Kapiris, Lance Larcombe, Victor Bray, Ben Bray, Gary Phillips, and Maurice Fabietti. During the summer months, because of rules similar to Pro Modified, such stars in the United States frequently appear during the North American winter during the International Hot Rod Association 400 Thunder series currently. For example, during the 2017-18 IHRA season, Texan Frankie "Mad Man" Taylor drove a second Bray Racing car when the drag strips closed for the winter.

Top Doorslammer originally started out as an exhibition class called Wild Bunch with notable pioneers John Zappia and Victor Bray. After a number of successful years of running the class, ANDRA recognised the class worthy of a professional bracket. By 1996 Top Doorslammer was officially recognised as a Group 1 class, and has since grown into one of the most successful brackets.

Television broadcasting Top Doorslammer Championship is on SBS Speedweek and the new SPEED Channel on Foxtel.
