"Crunch" is a chocolate bar made of milk chocolate and crisped rice. It is produced globally by Nestlé with the exception of the United States, where it is produced under license by the Ferrara Candy Company, a subsidiary of Ferrero. Nestlé "Crunch" was first introduced in 1938.

In the UK it was sold as "Dairy Crunch" from introduction in mid 1960s up to 1990s when it was rebranded as "Crunch".

In May 2013, Nestlé USA announced that Nestlé "Crunch" agreed to begin using 100% certified cocoa beans throughout the entire line of its standard "Crunch" bars for the first time. This plan came to fruition as part of the Nestlé Cocoa Plan, the company’s global initiative to help improve the lives of cocoa farmers and the quality of their products while assuring a sustainable cocoa supply for years to come.

In January 2018, Nestlé announced plans to sell its U.S. confectionery brands (including the U.S. rights to "Crunch") to Italian chocolatier Ferrero SpA, maker of "Nutella", for US $6.9 billion. Ferrero folded the acquired brands into the operations of the Ferrara Candy Company. The sale was rumoured to be because of low growth in the mainstream chocolate market due to newer competitors such as Kinder and the increased variety of snacks, making it challenging for mainstream candy bars like "Crunch".

Products sold to Ferrero include (but are not limited to) the "Crunch Bar", "Butterfinger", "Nerds", and "LaffyTaffy".
