Unilever is a British–Dutch multinational consumer goods company. Its products include foods, beverages, cleaning agents and personal care products. It is the world's third-largest consumer goods company measured by 2011 revenues (after Procter & Gamble and Nestlé) and the world's largest maker of ice cream.

Unilever is a dual-listed company consisting of Unilever N.V. in Rotterdam, Netherlands and Unilever PLC in London, United Kingdom. Both Unilever companies have the same directors and they operate as a single business. The current non-executive Chairman of Unilever N.V. and PLC is Michael Treschow while Paul Polman is Group Chief Executive.

Unilever PLC had a market capitalisation of £27.3 billion as of 23 December 2011, the 18th-largest of any company with a primary listing on the London Stock Exchange.

Unilever was founded on 1 January 1930 by Antonius Johannes Jurgens, Samuel van den Bergh and William Hulme Lever, 2nd Viscount Leverhulme.

The amalgamation of the operations of British soapmaker Lever Brothers and Dutch margarine producer Margarine Unie (a 1927 amalgamation of Anton Jurgens Margarinefabrieken N.V. and Samuel van den Bergh) made sound commercial sense, as palm oil was a major raw material for both margarines, and soaps, and could be imported more efficiently in larger quantities.
