Queens-Nassau Transit Lines was a bus operator in the borough of Queens in New York City. It began operating bus replacements for the New York and Queens Transit Corporation trolleys in 1937. The Salzberg family, dealers in scrap metal and a short line railroad operator, acquired the NY&QTC (originally the New York & Queens County Railway Company) for the purpose of replacing the street railway operations with buses and selling the scrap steel. They formed QNT as the operator of the lines, and the company was renamed Queens Transit Corporation in 1957.
