The Bowin P3 is a monocoque racing car that was produced in 1968 by Bowin. The P3 was designed for the Australian National Formula and the Australian 1½ Litre Formula. After the capacity limit for Australian Formula 2 was increased from 1100cc to 1600cc at the beginning of 1969, the P3 found a new home in that class. The car was designed by John Joyce, founder of Bowin and assisted by Ray Parson, better known as a mechanic. This was the only Bowin car type to come out of the Joyce-Parsons association. The project took just over 12 weeks to complete.
