4711 is a traditional German Eau de Cologne brand by Mäurer & Wirtz. Because it has been produced in Cologne since at least 1799, it is allowed to use the geographical indication Original Eau de Cologne. The brand has been expanded to various other perfumes and products besides the original Echt Kölnisch Wasser, which has used the same formula for more than 200 years.
The 4711-flagship store in the Cologne Glockengasse is a popular tourist attraction.

Eau de Cologne (German: Kölnisch Wasser; lit. “Water of Cologne”), or simply cologne, is a perfume originating from Cologne, Germany. Originally mixed by Italian-born Johann Maria Farina in 1709, it has since come to be a generic term for scented formulations in typical concentration of 2%–5% and also more depending upon its type essential oils or a blend of extracts, alcohol, and water. In a base of dilute ethanol (70%–90%), eau de cologne contains a mixture of citrus oils including oils of lemon, orange, tangerine, clementine, bergamot, lime, grapefruit, blood orange, and bitter orange. It can also contain oils of neroli, lavender, rosemary, thyme, oregano, petitgrain (orange leaf), jasmine, olive, oleaster, and tobacco.

In the early 18th century, Johann Maria Farina (1685–1766), an Italian living in Cologne, Germany, created a fragrance. He named it Eau de Cologne ("water from Cologne") after his new home. Over the next century, the fragrance became increasingly popular.
According to legend, on 8 October 1792, a Carthusian monk made a wedding gift for the merchant Wilhelm Mülhens (1762-1841): the secret recipe of a so-called "aqua mirabilis", a "miracle water" for internal and external use. Mülhens then founded a small factory at Cologne's "Glockengasse" and established the first "Eau de Cologne" as a remedy.
Peter Joseph Mülhens and his son Wilhelm Mülhens had been in a dispute over the use of the name "Farina" from 1800 to 1881. The Farina family accused Mülhens of using the name without authorization. The firm "Johann Maria Farina gegenüber dem Jülichs-Platz" feared confusion between the products because they also produced perfumes. In 1832, Wilhelm Mülhens lost the dispute, whereupon he employed another Mr. Farina from Mortara in order to continue using the name.
The company name was Eau de Cologne & Parfümerie Fabrik Glockengasse No. 4711 gegenüber der Pferdepost von Ferd. Mülhens in Köln am Rhein until 1990, when it was renamed Mülhens GmbH & Co. KG.

In 1994, the Mülhens family company was bought by Wella AG, Darmstadt, Germany. Since 1997, Wella has operated its cosmetic activities under the name Cosmopolitan Cosmetics GmbH, although the name Mülhens GmbH & Co. KG was still in use. In 2003, Wella AG was taken over by the American competitor Procter & Gamble.
In summer 2006, Procter & Gamble announced it would sell the 4711 brand and three other former Mühlens brands, as part of an effort to divest "local" brands and to focus on global brands. The offer attracted several interested parties; in December 2006, P&G announced that the brand had been sold to the perfume company Mäurer & Wirtz in Aachen, a subsidiary of the Dalli Group.
