Elmer Rosenberg (1885 – April 1951) was an American politician and labor leader from New York.
He was born in Újpest, which is now a district of Budapest, Hungary, and attended the public schools there. He emigrated to the United States in 1900, and became a cloth cutter in New York City. He graduated from Rand School of Social Science. He was President of Local 10 of the Amalgamated Ladies' Garment Cutters Union; and President of the Joint Board of the Cloak, Skirt and Reefer Makers' Union. He led several garment workers' strikes and frequently took part in negotiations of wages and working conditions between garment unions and manufacturers.
His son, Robert Rosenberg, (b. 1925) was a history teacher and hotel owner. His daughter Esterita "Cissie" (Rosenberg) Blumberg (1928–2004) published a book of memoirs: Remember the Catskills: Tales of a Recovering Hotelkeeper (1997).
