Gotofredo da Castiglione (sometimes given as Gotofredo II to distinguish him from Gotofredo I, Archbishop of Milan) was an Italian anti-bishop from 1070 to 1075, appointed by Henry IV, Holy Roman Emperor to the office of Bishop of Milan.^[1] This began the Investiture Controversy, whereby Pope Gregory VII excommunicated Gotofredo over the issue of lay investiture.^[2]

Gotofredo was eventually recanted as bishop after the Walk to Canossa in 1077.
