John Robert Fish ( – May 11, 1958) was a NASCAR Grand National Series race car owner whose career spanned from 1955 to 1958.

[1] He was the possible inventor of the "Iron Lung" (formally known as a negative pressure ventilator) for his wife who was suffering from circulation problems.

[2] Another occasion had Fish cable the President of the United States on a lecture about using a simple pressure box to rescue sailors on a submarine.

[2] Fish would eventually move to Florida where he could sell his products to wealthy game fishermen without the harassment he had back in California.

Today, NASCAR uses fuel injection, which has made carburetors obsolete in the Sprint Cup Series.
