UBM plc (LSE: UBM) is a global live media and business-to-business communications, marketing service and data provider, serving specialist business communities, principally to the technology, healthcare, trade and transport, ingredients and fashion industries. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The company was founded in 1918 as United Newspapers by David Lloyd George to acquire the Daily Chronicle and Lloyd's Weekly Newspaper. In 1929, the company merged with Provincial Newspapers, an owner of regional papers in the north; the next year, it sold its national papers. The company continued for decades as a regional newspaper publisher, making acquisitions such as Yorkshire Post Newspapers in 1969.

The history of the companies that now make up UBM stretches back almost two hundred years to the Journal of Commerce which was founded and first published by Samuel Morse in 1827. Today, the Journal of Commerce is produced in both print and digital formats by UBM Global Trade. UBM businesses still publish many other titles that were launched in the 19th century, including Building magazine, launched in 1843 by Joseph Hansom, as well as Chemist & Druggist.
