Koilonychia, also known as spoon nails, is a nail disease that can be a sign of hypochromic anemia, especially iron-deficiency anemia. It refers to abnormally thin nails (usually of the hand) which have lost their convexity, becoming flat or even concave in shape. In early stages nails may be brittle and chip or break easily.

Koilonychia is associated with Plummer–Vinson syndrome and iron deficiency anemia. It has also been associated with lichen planus, syphilis, and rheumatic fever. The term is from Greek κοῖλος (koilos) 'hollow' and ὄνυξ (onyx) 'nail'.
