Knopsvanen er en andefugl, der har sin primære udbredelse i Europa og det vestlige Asien. I Danmark er knopsvanen en almindelig ynglefugl og derfor den bedst kendte af de tre svanearter, der ses i landet.

Very large all-white swan with an orange bill carrying a black basal knob; often holds the neck in a gentle S-curve and raises the wings like sails.
