J. G. Niederegger GmbH & Co. KG is a producer of marzipan and sweets which is based in Lübeck, Germany.

By the 19th century, marzipan, traditionally the choice of kings and queens, was becoming popular with the ordinary people of Lübeck.

Johann Georg left in 1806 to set up his own shop, and the products he produced were of such high quality that they were sought out by kings and emperors.

[1] In the town center of Lübeck, opposite the Town Hall, the always-crowded Café Niederegger, known as the "harem confectionery", offers a café, a shop for Niederegger sweets, and a marzipan museum on its upper floors.

Niederegger's many customers have included the writer, and son of Lübeck, Thomas Mann.
