Atto of Pistoia (Portuguese: Santo Atão; 1070 – 22 May 1153) was a Portuguese Roman Catholic bishop and a professed member from the Vallumbrosan Order as well as the Bishop of Pistoia and a noted historiographer.

He was born at Beja in the Portuguese region of Alentejo in 1070. He became Abbot of Vallombrosa (in Tuscany) in 1105, and in 1135 was made Bishop of Pistoia, also in Tuscany. He wrote lives of John Gualbert and Bernard degli Uberti, bishop of Parma. In 1145 he transferred to Pistoia certain relics of the Apostle James the Great. His correspondence on that occasion is found in Ferdinando Ughelli, Italia sacra, VII, 296.
