'''Kerang geoduck''' ({{IPAc-en|ˈ|ɡ|uː|i|ˌ|d|ʌ|k}} {{respell|GOO-ee|duk}}; ''Panopea generosa'') adalah spesies kerang air asin yang sangat besar dalam genus ''[[panopea]]'', famili [[Hiatellidae]].<ref name="WoRMS">{{WRMS species|545994|''Panopea generosa'' Gould, 1850||28 December 2010}}</ref><ref name=Vadopalas/> Nama "geoduck" berasal dari nama Lushootseed, yakni ''gʷidəq''.
Kerang ini berasal dari perairan pesisir timur Samudra Pasifik Utara, dimulai dari Alaska hingga [[Baja California]].<ref name=Vadopalas/> Panjang cangkangnya berkisar antara 15 cm hingga lebih dari 20 cm, tetapi sifon yang sangat panjang membuat kerang ini sendiri lebih panjang dari "leher", atau sifonnya saja bisa mencapai 1 meter. Geoduck adalah kerang penggali terbesar di dunia.<ref name=BBC>{{cite web |author1=Morgan, James |title=The 'phallic' clam America sells to China |url=https://www.bbc.co.uk/news/magazine-33261666 |publisher=BBC |access-date=20 July 2015 |date=19 July 2015}}</ref> Kerang ini juga merupakan salah satu jenis hewan yang berumur paling panjang, dengan rata-rata umur 140 tahun,<ref name=Orensanz>{{cite journal | last1 = Orensanz | first1 = J.
