Leucoplasts (also leukoplasts) are colorless plastids found in endosperm, tubers, cotyledons, roots and other non-photosynthetic tissues of plants.

They serve various functions, for example, storage of starch, lipids, or proteins. Plastids of these three types are respectively known as amyloplasts, elaioplasts, and proteinoplasts. A leucoplast may also perform biosynthetic functions such as the synthesis of fatty acids, amino acids, and various other compounds.

Although they vary in shape, a leucoplast is usually much smaller than a chloroplast.
