The National Super Sedan Series was a Dirt track racing series held in Australia for Super Sedans and was sanctioned by the national controlling body, the Australian Saloon Car Federation (ASCF).
Inaugurated in 2006, the series was separate to the Australian Super Sedan Championship.
The winner of the 2006 series was Queensland driver Wayne Randall.
The 2008/09 Australian Champion has won the NSSS on five occasions with one second- and one third-place finish.
South Australian veteran Bill Miller, who in his families tradition in Super Sedans drives a pink coloured car as did his mother Joan (who started racing in a Mini at Adelaide's old Rowley Park Speedway in the 1960s) and older brother Stephen, is the only driver to have driven in every single round of the National Super Sedan Series since its inception in 2006.
