Quality Street is a line of tinned and boxed toffees, chocolates and sweets, first manufactured in 1936 by Mackintosh's in Halifax, West Yorkshire, England.

In 1890, John Mackintosh and his wife opened a shop in Halifax, West Yorkshire, England where they created a new kind of sweet by mixing hard toffee with runny caramel.

Harold Mackintosh set out to produce boxes of chocolates that could be sold at a reasonable price and would, therefore, be available to working-class families [citation needed].

Individual larger versions of the more popular chocolates are now manufactured and sold separately, as an extension to the brand, such as a bar based on the Purple One.

Quality Street gained the implied endorsement of Saddam Hussein when the Iraqi leader was reported to have offered them to visiting British politician George Galloway in 2002.

Following a suggestion by packaging manufacturer William T. Robson OBE, a new barrier material of foil backed paper was adopted by Mackintosh in 1967 to overcome the problem.

[citation needed] In 2022, Nestlé announced that they would replace plastic wrappings with recyclable paper versions, with the intention of keeping two billion wrappers a year out of landfill.
