Calcium acetate  is a calcium salt of acetic acid with the chemical formula C₄H₆CaO₄. Calcium acetate is also called Acetate of lime or Calcium ethanoate or Calcium diacetate. It is widely used as a hydrate in treating hyperphosphataemia and functions as a chelator.

It is hygroscopic in its anhydrous form and monohydrate in the common form. A mineral such as calcium is required for many cellular functions such as nerve impulse transmission, cardiac function, cell membrane permeability, muscle contraction, and bone formation. Calcium acetate is taken orally to treat or prevent calcium deficiency as well as to treat hyperphosphatemia as it has excellent phosphate-binding properties.
