Edward Dean Jeffries (February 25, 1933 – May 5, 2013) was an American custom car designer and fabricator, as well as stuntman and stunt coordinator for motion pictures and television programs based in Los Angeles, California.

Jeffries was born to Viola Irene (née Allison) and Edward James Jeffries in Osage, Iowa. After the family moved to Compton, California, Jeffries grew up in Compton and then neighboring Lynwood, California, where his father was a mechanic. He was the middle child, born between older sister Darlene Ann (b. May 18, 1931, Osage, Iowa-) and younger sister Evonne Mae (b. December 2, 1935, in Osage, Iowa). A brother, James Eddie, was born December 2, 1935, in Osage, a twin to Evonne, but died the next day.

Jeffries served in the United States Army during the Korean War, stationed in Germany. While in Germany he saw fellow soldiers and locals custom painting their motorcycles, and this led him to pinstriping. As a young man, after returning from Germany, he started doing pinstriping on the side, while working as a grinder in a machine shop. As the striping took off he opened a custom pinstriping shop that would become famous with the Hollywood film industry.

A neighbor of Jeffries, race car driver Troy Ruttman befriended him, and they worked on cars together. After Ruttman joined with J. C. Agajanian, the Indianapolis 500 race team and Ascot Speedway owner, Agajanian hired Jeffries to stripe and letter his cars in 1953.

Actor James Dean was one of his early customers, and Jeffries painted "Little Bastard" on Dean's Porsche 550 Spyder. Jeffries recalled the day in September, 1955: "Jimmy knew that I was a pinstriper and had met me through Lance Reventlow and Bruce Kessler. He drove to my Lynwood shop in his new 550 and asked me to paint a temporary number 130 on the front hood, rear deck lid, and both doors of the Spyder in flat black, washable paint. He also asked me to paint "Little Bastard" on the tail section in the same font script. I painted it with One Shot, a gloss black enamel paint, as this would be permanent. It turned out great. Jimmy thought that the "Little Bastard" looked so cool across the bottom of the tail section."

As an extra reward for working on his cars, and to have him on hand there, Agajanian took Jeffries to the 1952 Indy 500. Noticing his unusual painting and pinstriping style, Mobil Oil hired him in the following years to paint many of the Indy race cars. It was free to the teams and Mobil got their logo somewhere on the car. Jeffries would paint and pinstripe the cars and helmets of race car drivers like Jim Rathmann, Parnelli Jones, and A. J. Foyt, and became Foyt's paint and body man. After that, in 1962, he worked for famous race car designer and builder Carroll Shelby on the Cobra. He would go on to become one of the best custom car painters of the late 1950s and early 1960s, and an early pioneer of painting flames on cars. He also developed his own paint, Jeffries Indy Pearl.

Jeffries was a certified welder and custom-built vehicles used in numerous Hollywood productions through his company, Dean Jeffries Automotive Styling, in Los Angeles.

He began custom fabrication in the 1960s, expanding his premises three times in the decade. He built The Mantaray (which took the Best Experimental car award at the 1964 Pomona car show and appeared on Steve Allen's The Tonight Show, and in Bikini Beach), Python (a prototype for Ford), Black Beauty (from The Green Hornet), the Monkeemobile, the Landmaster from Damnation Alley (1977), the Moon buggy (that James Bond steals in Diamonds Are Forever), the trolley (from Who Framed Roger Rabbit). Jeffries was also an expert on dune buggies, produced his own models, and has contributed to books about them. He did all of the custom fabrication work on the movie Convoy in Albuquerque, New Mexico, where he rented the shop from Burns Truck & Parts. Jeffries is credited as the constructor of the five cars attempting to drive across the U.S. in the 1975 film, Death Race 2000.
