thumb|200x200px|Thick elastic fibers consisting of bundles of elastin in the human lung Elastin is a protein encoded by the ELN gene in humans and several other animals. Elastin is a key component in the extracellular matrix of gnathostomes (jawed vertebrates). It is highly elastic and present in connective tissue of the body to resume its shape after stretching or contracting. Elastin helps skin return to its original position whence poked or pinched. Elastin is also in important load-bearing tissue of vertebrates and used in places where storage of mechanical energy is required.

A elastina é uma proteína de função estrutural que forma fibras elásticas. Costumam ocorrer em lugares como o pavilhão auditivo, o conduto auditivo externo, a trompa de Eustáquio, a epiglote, a cartilagem cuneiforme da laringe e nas artérias elásticas. Normalmente, têm uma coloração amarelada. A elastina se caracteriza por formar fibras mais finas que aquelas formadas pelo colágeno. Essas fibras cedem bastante à tração, mas retornam à forma original quando é cessada a força. Essa propriedade é responsável pela manutenção da pressão sangüínea nos períodos de diástoledo ventrículo esquerdo, ou seja, quando o sangue não está saindo do coração. A Elastina confere a estas fibras elasticidade e resistência.
