Robert Dunham (July 6, 1931 – August 6, 2001) was an American actor, entrepreneur, writer, racecar driver, journalist, and a US Marine.

Dunham was an American living in Japan during most of the country's "Golden Age" of cinema, and worked in films directed by Ishirō Honda, Jun Fukuda, and Kinji Fukasaku.

After being honorably discharged from the Marine Corps., Dunham decided to stay in Japan and opened up his own import/export business.

[1] Dunham lived in Tokyo for 22 years, with a Japanese wife Keiko, and their two children, Barbara Ann and Daniel.

The relationship ended after Miller moved back to the United States and Dunham claimed to have "lost track of her" after having kept up correspondence via postal mail for a time.
