William O. Tiron. (died early 1290s) was a late 13th-century Tironensian abbot and bishop in the Kingdom of Scotland. He appears in the extant sources for the first time on 25 April 1276; he is Abbot of Arbroath. According to the Scotichronicon the work of the 15th-century historian Walter Bower William’s predecessor Adam de Inverlunan had died in 1275 so William probably became abbot in either that year or in 1276.William was abbot until 1284 when he was elected to be Bishop of Dunblane.
