130px|thumb|An ester of a carboxylic acid. R stands for [[hydrogen, halogen or organyl and R stands for any organyl group.]] In chemistry, an ester is a compound derived from an acid (either organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group () of that acid is replaced by an organyl group (R). These compounds contain a distinctive functional group. Analogues derived from oxygen replaced by other chalcogens belong to the ester category as well. According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides
An ester is a chemical compound formed when the hydrogen atom in an acid is replaced by an organic group, creating a molecule with a distinctive structure. Esters are important because they occur widely in nature and industry—for example, they make up fats and oils, and they're used in fragrances, plastics, and many other everyday products.

Los ésteres son compuestos orgánicos derivados de petróleo o inorgánicos oxigenados en los cuales uno o más grupos hidroxilos son sustituidos por grupos orgánicos alquilo (simbolizados por R'). Etimológicamente, la palabra "éster" proviene del alemán Essig-Äther (éter de vinagre), como se llamaba antiguamente al acetato de etilo.
