Maurus Xaverius Herbst or Florian Johann Friedrich Herbst (14 September 1701 – 4 April 1757) was a German Benedictine abbot.

In 1704 his home town of Pleinfeld was under French occupation during the Spanish War of Succession.

When the imperial troops, who had been quartered in the village, had to retreat, one of the soldiers took the young Herbst with them.

In the diocese of Eichstätt, there is a veneration of saints around Maurus Xaverius, as he is attributed several healings.
