El abductor del quinto dedo es un músculo intrínseco del pie. Se encuentra dentro de la primera capa muscular plantar (la más superficial) del pie. Inserciones: se origina en los tubérculos medial y lateral del calcáneo y en la aponeurosis plantar. Se inserta en la base lateral de la falange proximal del quinto dedo. Acciones: abducción y flexión del dedo pequeño del pie. Inervación: nervio plantar lateral (rama del nervio tibial). Irrigación sanguínea: arteria plantar lateral.
