SoHo is a neighborhood in the New York City borough of Manhattan. It is bounded roughly by Houston Street on the north, Lafayette Street on the east, Canal Street on the south, and Varick Street on the west. The name is an acronym for South of Houston (pronounced HOUSE-tin) Street, and has no relation to the Soho district of London, England. Its name has been the model for other new neighborhood descriptions in New York City, such as TriBeCa and DUMBO. Before its incarnation as a trendy locale, it was known as the Cast Iron District.
