Bertold of Landsberg (before 1464 – 4 May 1502 at the castle in Rotenburg an der Wümme) was bishop of Verden.

From 1468, he administered the bishopric on behalf of Bishop John III of Asel, who suffered from ill health.

In 1470, the cathedral chapter urged John III to abdicate and elected Berthold as his successor.

Berthold concluded a treaty of alliance for a twenty-year period with Duke William I of Brunswick-Wolfenbüttel, who had been his predecessor's greatest enemy.

In 1483, the cities of Brunswick and Hildesheim defeated Duke Henry VII of Brunswick-Lüneburg at Bleckenstedt in 1483.

In 1488, Berthold travelled to Rome to object to an unjustified papal ban against the bishoprics of Verden and Hildesheim.

In 1500, a nobleman from the Schwichelt family convinced the pope to pronounce a ban against the church in Hildesheim again.

Because of the unsettled conditions in Hildesheim, Berthold resided mostly in the castle of Rotenburg an der Wümme in the Bishopric of Verden.
