Sigmund Neufeld (May 3, 1896 – March 21, 1979) was an American B movie producer. He spent many years at Poverty Row studio Producers Releasing Corporation where he mainly produced films directed by his brother Sam Newfield. When PRC was taken over by Eagle-Lion Films in 1947 they both left the company. Eagle-Lion had goals of making bigger, more ambitious movies, a change in strategy that Sigmund deemed to be a financial mistake. During the following years he and his brother made several films for Film Classics. When this company also merged with Eagle-Lion in 1950 they both moved to Lippert Pictures.
