Steve Bing (b. March 31, 1965) is an American real estate developer, film producer, and philanthropist. At the age of 18, he inherited a $600 million real estate business from his grandfather, Leo Bing , and dropped out of Stanford University shortly thereafter.

He dated actress Elizabeth Hurley from 2000 to 2001, and is well-known for his dispute over the paternity of Hurley's son born in 2000. He denied he was the father, but DNA tests later confirmed his paternity. He was also involved in a breach of privacy suit with MGM CEO Kirk Kerkorian related to the paternity of Kerkorian's wife Lisa Bonder's daughter.

In the 2004 election cycle, Bing has donated more than $16 million to the Democratic Party and allied groups.
