Rieber & Søn is a Norwegian food manufacturing company that owns and produces a wide range of products and brands.

Brands owned by Rieber include Toro, Denja, Mr. Lee, Vossafår, Vestlandslefsa, Geisha, Ming, Trondhjems (Norway), Mrs. Cheng’s, Frödinge (Sweden), Puttkammer & Walke (P&W) (Germany), Wolfgang Kornke's Finest Food (Austria), K-Salat, Bähncke (Denmark), Vitana (Czech Republic and Slovakia), Chaka (Russia), Cronions and Rijnhout (the Netherlands).

A new business area is acquired through the production of substitute coffee in 1933 and in 1946 the TORO brand is launched.

Two years later it merged with the building materials companies Jacob Neumann and Nodest Industrier and floated on the Oslo Stock Exchange.

In 2000 the building materials section was sold and the company chose to concentrate only on food production.
