Wolfgang von Dalberg (1538 – April 5, 1601) was the Archbishop-Elector of Mainz from 1582 to 1601.

When the cathedral chapter of Mainz Cathedral met on 19–20 April 1582 to elect a new Archbishop of Mainz, Dalberg narrowly beat out Julius Echter von Mespelbrunn, Bishop of Würzburg to become the new archbishop.

Pope Gregory XIII confirmed his election on 3 September 1582.

Although a firm Roman Catholic, Dalberg strove for reconciliation with the Protestants.

Dalberg died in Aschaffenburg on 5 April 1601 and is buried in Mainz Cathedral.
