Calcitonin is a 32 amino acid peptide hormone secreted by parafollicular cells (also known as C cells) of the thyroid (or endostyle) in humans and other chordates^[5] in the ultimopharyngeal body.^[6] It acts to reduce blood calcium (Ca²⁺), opposing the effects of parathyroid hormone (PTH).^[7]

Its importance in humans has not been as well established as its importance in other animals, as its function is usually not significant in the regulation of normal calcium homeostasis.^[8] It belongs to the calcitonin-like protein family.

Historically calcitonin has also been called thyrocalcitonin.^[9]
