Joseph Washington Frazer (March 4, 1892 – August 7, 1971) was a mid-20th century American automobile company executive.

Over the course of his life Frazer was employed in half a dozen different companies as a mechanic, instructor, financier, salesman, president and board chairman.

He held down top executive positions in Chrysler, Willys-Overland, and Graham-Paige, before partnering with Henry J. Kaiser to form the Kaiser-Frazer Corporation.

Frazer was then hired by General Motors, where his understanding of purchase loans made him a key organizer of GMAC.

On loan from GM's executive staff, he established a similar lending arm for Pierce-Arrow Motor Car Company.

[5] Frazer suggested to Chrysler that the company build a low-priced car that would directly challenge Ford and GM.

During his time at Willys the company built and unveiled its new military vehicle, where Frazer approved trademark filings to make "Jeep" an automotive nameplate.

[13] He announced that the company would resume manufacturing automobiles after the war with a completely new car to be called the Frazer.

While seeking financial backing for this venture, he met industrialist Henry J. Kaiser, who also had plans for a postwar automobile.
