Elastic fibers (or yellow fibers) are bundles of proteins (elastin). These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed. Elastic fibers include elastin, elaunin and oxytalan.

Elastic tissue is classified as "connective tissue proper".


Elastic fibers are found in the skin, lungs, arteries, veins, connective tissue proper, elastic cartilage, periodontal ligament, fetal tissue and other structures.
