Acesulfame potassium (ace-SUHL-faym), also known as '''acesulfame K ' (K is the symbol for potassium) or Ace K, is a calorie-free sugar substitute (artificial sweetener), and marketed under the trade names Sunett and Sweet One.

In chemical structure, acesulfame potassium is the potassium salt of 6-methyl-1,2,3-oxathiazine-4(3H'')-one 2,2-dioxide. It is a white crystalline powder with molecular formula CHKNOS and a molecular weight of 201.24 g/mol.
