Adolf of Egmond (Grave, January 12, 1438 – Tournai, June 27, 1477) was a Duke of Guelders, Count of Zutphen from 1465–1471 and in 1477.
He was the son of Arnold, Duke of Guelders and Catherine of Cleves.
In the battle of succession for Guelders, he imprisoned in 1465 his own father and became Duke with the support of Philip the Good, who also made him Knight in the Order of the Golden Fleece. In 1468 he won the Battle of Straelen against Cleves, but Charles the Bold reinstated his father Arnold, and Adolf was imprisoned in Hesdin.
After the death of Charles the Bold in 1477, he was liberated by the Flemish.
He died the same year at the head of a Flemish army besieging Tournai, after the States of Guelders had recognized him as Duke.
