The Matich name was applied to a series of sports racing cars and open wheel racing cars produced in Australia between 1967 and 1974 under the direction of Sydney-based racing driver and engineer Frank Matich.
The Matich SR3 was a Group A Sports Car built for Matich by Bob Britton in 1967. It was powered by an Oldsmobile V8 engine and was driven to victory by Matich in the 1967 Australian Tourist Trophy, Australia's premier sports car race of that year. Later in the year, Matich raced in both the US Can-Am series and in Australia, with two SR3s fitted with 4.4-litre Repco V8 engines. Matich won the 1968 Australian Tourist Trophy with a Repco powered SR3.

A completely new design, the Matich SR4, was produced with designer-frabricator Henry Nehrybecki for 1969 utilising a quad cam Repco 740 V8. Matich dominated the inaugural Australian Sports Car Championship in that year, winning all three heats with the SR4.
