Dairylea is a brand of processed cheese products produced by Mondelēz International and sold in Ireland, the United Kingdom and Australia.

It used the slogans "Kids will eat it until the cows come home" and "Kids will do anything for the taste of Dairylea" in a series of adverts on UK television showing children trading toys and other items of value, or doing dares for Dairylea Triangles.

Dairylea has been made at Mondelez International's Namur production site south of Rhisnes, La Bruyère, north of Namur, the centre of Wallonia (the south of Belgium).

Dairylea triangles are packaged in a cardboard 'wheel' and opening it reveals the foil-wrapped soft cheese product portions.

In the early 21st century, Dairylea Lunchables were advertised as being "full of good stuff", though the product contained high amounts of salt and saturated fats.
