Giselbert I of Bergamo (died c.927/929) was a northern Italian nobleman.
Giselbert I was originally a vassal of Berengar I of Italy.
Yet by 922 he supported Rudolph II of Burgundy, who rewarded him with the position of count of Bergamo (923).
[1] When Rudolf fell from favour, Giselbert I changed allegiances once again.
By 926 he was invested as count palatine of Bergamo by the new king, Hugh of Italy.
