Harry Donenfeld (October 10, 1893 – February 1965) was an American publisher who is known primarily for being the owner of National Allied Publications, which distributed Detective Comics and Action Comics, the originator publications for the superhero characters Batman and Superman. Donenfeld was also a founder of the Albert Einstein College of Medicine.

Harry Donenfeld was born into a Jewish family in Romania, and at the age of five emigrated to the United States of America with his parents and his brother Irving. A few years later the family was joined by Harry's two elder brothers Charlie and Mike. Little is known of his early life, as is common with many people entering America during the days of mass immigration; but the family entered America via Ellis Island and took up residence in New York in the Lower East Side area.

Donenfeld spent his early life in and out of school, and later in and out of gangs, refusing to settle down and find an occupation like his brothers, who had set up a printing enterprise. Harry became a clothing salesman working in the city, and saw himself as a class above the ordinary working man, and wanted a better life, but preferably without the hard work. After he avoided the draft in 1917, he married Gussie Weinstein in 1918, and thanks to a loan from her parents he was able to open a clothing store in Newark, New Jersey.
