Saint Peter Igneus, Italian Benedictine monk
Pietro Igneo (died 11 November 1089) was an Italian Roman Catholic Benedictine monk from the Vallombrosians branch. He also served as a cardinal and was named as the Cardinal-Bishop of Albano. He is often referred to as a member of the Aldobrandini house but this familiar denomination is not attested in sources as a fact.

Igneo's beatification had been confirmed on 4 March 1673.
